TestMy itself has plenty of bandwidth. Not sure if your speed tests were taken on the same day and time. I've seen speeds be 30% lower here during peak usage hours, at times on weekends. Get an average of multiple tests on both machines over a period of days, and take the readings at the same time of day on both. See if there's a common trend for time of day. If you're using wireless between your device and the cable modem, make sure you are at the same distance from the wireless point each time. The gf speeds are the same as mine on that 50/5 plan. I assume from your description that the two PCs are the same. Also select fixed test sizes by doing the Download test (like 50 MB down, and 5 MB up.) each time rather than the express test for this data taking. I see speeds at 30% lower than my 50Mbps typical that I get during off hours. I'm roughly in the middle between the Dallas and Washington servers. Sometimes it's slower on one, sometimes the other. Many times when I get a slow reading, I'll get a faster one only minutes later which makes me think that whoever TWC uses as a supplier of the backbone, somewhere along the path there's congestion. You can set up an auto test.

After about 8 months now, the service is still pretty solid. During busy hours and especially on weekends, the download rates are down from close to 50 Mbps to the lower mid-30s to low 40s on average, but there are a lot more short term low readings going on where the test plot shows dips down below 20 and sometimes in the single digits. There must be a ton of people now eating bandwidth compared to a year or two ago. Off hour weekday averages are in the 50-54 Mbps range. ....on my wired 2010 iMac But the path that TWC is using from Cincinnati to the TestMy server in Dallas is a lot slower than the one to Washington, DC

After the large number is Mbps (mega bits per second, which is million bits per second). The next number is the number of 8-bit bytes so it's the Mbps divided by 8, and it's shown in MB/s which means mega bytes per second. A byte is an 8-bit digital word made of of 8 bits. At least that's what I think you were asking about.

I don't have any detailed knowledge about it. I too read up on it a little when I was researching gigabit Ethernet switches, where some of them supported Jumbo Frames and some didn't. I ordered one that supported it. I can't remember for sure if all my other equipment supported it though, and I can't remember if Time Warner actually uses them. Sorry I wasn't of any help.

Welcome from Southwest Ohio in the US. And CA3LE, what's the tool that you just released?

i don't do it very often either, maybe twice a year. i don't buy any 3rd party clean-your-Mac or speed-up-your-Mac kind of software. i used to buy that stuff but the benefit per dollar spent per year on it never seemed to be worth it. the safe boot along with disk utility has served me well for a long time now just as periodic checker-tweakers. the only real issues i've had in years have been related to iCloud syncing across 3 devices (two iOS and one Mac) where one or more of them will not be the same-like Reminders or Calendars. iCloud is still pretty new. and Apple's support forum has some pretty sharp people that provide answers pretty quickly. the level 8 thru 10 guys there usually have the right answer, and they are more familiar with where certain Apple support documentation is. one lesson i learned was - don't knock a Firewire cable out out of a peripheral drive during a Time Machine backup. the cable came out of one drive in the last drive in the chain (and it wasn't the Time machine backup drive). the result was pretty ugly. the backup volume got corrupted, and i had to format it. the last drive in the chain wouldn't even mount until i not only powered down the computer but had to de-power all the firewire drives. the lesson learned was when you have a house cleaning service person come, shut EVERYTHING down.

From Apple's support site: http://support.apple.com/kb/HT1564

I'm not sure what exactly happens when you boot in safe mode, but I've seen comments on Apple's Discussion Forums where for some odd problems, they have recommended doing it. I'm guessing it clears out caches, zaps p-ram ? I don't know if it does anything outside of the System folder. I should probably read up on it. Every once in a while I do it "just because". Haha. If you had a bootable OS on an external drive it would be interesting to compare the drive speeds. I don't think the HDDs they put in the laptops are particularly fast, their usually low power designs at 5400 rpm. Not sure about hers. I'm not sure it'll be very easy to replace that HDD. Check iFixit for that model.

How full is the HDD?

Try shutting down, then restarting in safe mode. Hold shift key down when you hear the startup chime. This cleans out some stuff. If you can, boot from another HDD with a clean install OS and see if that makes a difference. You can look in the main root directory Library and see if there are any odd looking files in the LaunchAgents and LaunchDaemons folder. Not the Library in the System folder, but the Library folder at the top level of the int HDD.

Holy crap. Must be a limitation of my AEBS + Cable Modem/ISP plan. My plan is 50 max and I exceed that (53-54 at times) on my wired iMac. But I've only seen low-mid 40s on my wireless. I have 7 things hooked to the 802.11n AEBS. Don't know if that slows it down a little or not. Even when I'm standing right next to the AEBS I rarely see above 42-43.

The 42 Mbps you got looks like what might be about the max throughput for the iPhone 5s. That's about what I get on the 5s using WiFi thru my AirPort Extreme Base Station 802.11n. The AEBS is hooked to a 100 Mbps router and then the 100 Mbps cable modem. When I'm getting about 42 on the iPhone with Wifi, my Ethernet wired connected iMac gets about 52-54 Mbps, the max of my plan.....I only get that consistently from about midnight to 8 AM. When I run the iMac with WiFi running and Ethernet disconnected, I get the same numbers as with it wired. So I think the 42 Mbps number is about max for that phone. Amazing that you can get that on a phone connection. With my AT&T LTE, I'm getting about 11 Mbps avg on the iPhone. That's about 3-4x faster than my IPhone 4 was on AT&T. If I remember right, it usually came in at about 3 Mbps.

Ca3LE. Can't wait.

What extension is on the 319 MB file?

Hello from SW Ohio

Are you connecting via wireless or Ethernet? If wireless, connect via Ethernet and see if it acts the same.

Thanks for the info. Certainly looks like my power levels and SNR are fine.

Just wondering if the downstream levels were too high? I've seen them at over 6 dBmv. Been having erratic operation lately. Wondering if levels are high enough to cause distortion. When things were working better, they were down in the 4-4.5 range Also, I see Uncorrecables now and then. I don't know what they are, or the ramifications Or Correcteds for that matter

I got a similar response from my ISP: “things test fine to our infrastructure, we can’t control the rest of the Internet, we don’t know what to tell you.” when I was having similar issues. The very name Internet Service Provider means that they're selling more than just the connection. They are supposed to be managing how their customers are being routed. I don't know how they do that (contracts with other ISPs?) but they will do something if enough customers complain. "Miraculously" one day, they upgraded their service and things got 2-3x better, until just recently when things have begun to slow down again. You might try to find out who their other customers are and get a read on what their performance has been. If theirs too has been slow, get them to call in an issue. If theirs has been fast, ask the ISP what the difference is between you and them. Here's what Testmy's comments are on Speedtest.net https://testmy.net/ipb/topic/28902-why-do-my-results-differ-from-speedtestnet-ookla-speed-tests/

The numbers showing in my signature are a little dated. I just pulled up my 30 day averages and my wired iMac is at 48.9 / 5.3, and my older iPad 2 is at 27.3 / 4.3 on wireless. Amazingly my iPhone 5s is almost as fast as the wired iMac when on WiFi. iOS 7 Safari runs slower on the iPad 2 than it did in iOS 6.

Hi from SW Ohio. Just FYI. I have Time Warner's 50 Mbps down and 5 Mbps up plan, and I consistently measure slightly above both those rates on my home Ethernet and Wireless through their 100 Mbps cable modem And that's as measured here on TestMy.

Thankfully, the major video streaming sites make apps for iOS devices and Flash isn't used. The apps are pretty good. They really only have to do a couple of things. Browse for videos, organize your list, and stream. They may lack a feature or two, but overall they are good. If there's an equivalent Android app, I wouldn't think the experience would be much different - don't know, I don't own one. I don't know if they're Flash free either. I would think they'd be Flash free to help the users save battery life. I get more Flash updates for security patches than any other software on my iMac. Not a good sign. The only bad thing about the Adobe Flash update site tips that the design is somewhat simple and has been copied to the point where identifying a counterfeit is very hard. I go into a state of terror every time I see one of the "a Flash update is available" messages come up.

What kind of up and down speed are you registering on this site? You might want to test 2 to 3 times consecutively, using the Dallas server. Then repeat this at 4 to 6 hour intervals. After a couple of days you can see what your average is now. You can look at this site's database - the Database pull down menu. Or go here for Brazil. https://testmy.net/country/br. Also go here: https://testmy.net/country/br and pick the ISP rank tab. You can view the Oi and Virtua data. Virtua data looks faster, but like you say, you don't know if that's because most of the Oi data tests were run by people with an inexpensive slower service. You might call Oi and ask them to run some tests on the TestMy.net site and see what they get for results and compare that to your results now on Virtua. Not sure if they'd do that, but it might be worth a try. You might want to go to their office and sit with someone and try the TestMy site. Maybe take your laptop? Not sure if they'd do anything like that, but it might be worth asking.

Hi from SW Ohio

Mine seems OK with it. I just installed a Flash update a few days ago but haven't spent much time on the computer since. Mostly on the iPad. I agree about developers and Flash. It's terrible for mobile devices. Even MS and Adobe have admitted as much. Why in this day web page designers still use Flash is beyond me. It's like they don't know that 20% of the people surfing the web are using devices that don't run it. Whenever I run into a page that won't run because it needs Flash, I copy/paste my standard message back to their feedback link. Here it is. Feel free to use it. Your lack of support for iOS devices is unconscionable at this point. Requiring Adobe Flash is holding you back. The number of iOS devices that are your potential customers number close to 1/2 billion.....that's 1/2 BILLION !!!!!! The world is changing and you're not changing with it. Most of the top Internet sites realize this and have updated their services to not require Adobe Flash. Adobe itself recognizes that Flash isn't suitable for mobile devices, and are no longer updating it for Android. Microsoft Windows 8 will have only limited support for it. Yes there's costs associated with updating your site but if even if only 0.1% of the 1/2 billion users that are sign up with you, that's 500,000 new customers. Your advertisers will pay for the upgrade to your site. We use our iPads and iPhones almost exclusively now. We only get on our desktop and laptop computers to do the heavy duty stuff. Looking at your web based services is not the heavy duty stuff. We want to be able to have fully functional sites on our browsers too; not a cheesed down app that doesn't give the user everything the full site does. When mobile device users see a website, and the first thing they see is a message telling them they need Adobe Flash and they can't use it on their device, they immediately close that browser page, and go to a page that doesn't require it. Mobile users would never bookmark a mobile unfriendly site. Mobile devices are fast replacing newspapers and magazines and the number of users looking at websites on mobile devices is rapidly dwarfing the desktop computer web-browsing population. And before long, few if any mobile devices will run Flash because it is a processor and battery eating piece of software with security vulnerabilities. What's your rationale for having a website where the majority of the web-browsing population sees nothing but "Adobe Flash Required" or the page controls don't work.? Requiring Flash on your website puts you in the same position as the buggy whip makers once cars took over in the early 20th century. Flash is 1990s technology. Move on and stay in business. I think since I wrote that a couple of years ago, the number is more like 700 million now
