Wow, My speedtest problems have been solved

Recommended Posts

I have Verizon Fios 75 down and 35 up.  I have been doing speedtests since I have gotten my upgraded service.  I live in VA and been having alot of speedtests flucuations just from the DC server.  Only a third of the time I get the speed I should be getting which is 88 down from DC.  When I speedtest to texas I get about 35 and to the west servers I get about 15 down.  I dont even want to try the overseas servers.   I just found this link on the web today to improve network performance.  I followed all his steps and then went back on testmy.net and tried the same servers I have been trying before.  Now I get 88 down from every server in the US.  I went and tried the amsterdamn server just to see if it isn't a fluke and I got 50 down from amersterdam.  Here is the link if anyone else is having issues with testmy.net not even coming close to what your paying for.  




*note* I didn't adjust the jumbo packet option because I didn't have that option on my desktop or laptop NIC.  I just adjusted the other two options.

IMHO home users should not change Jumbo packet size, most if not all home routing equipment has 1514 set as the default and more importantly few if any ISP connections support anything over 1514 MTU.




The key concept to keep in mind is that all the network devices along the communication path must support jumbo frames. Jumbo frames needs to be configured to work on the ingress and egress interface of each device along the end-to-end transmission path. Furthermore, all devices in the topology must also agree on the maximum jumbo frame size. If there are devices along the transmission path that have varying frame sizes, then you can also end up with fragmentation problems. Also, if a device along the path does not support jumbo frames and it receives one, it will drop it. 



Turning IPv6 might help if your ISP has less than ideal IPv6 routes over the internet, currently it should be safe to disable it if it helps. (for a couple more years anyway) - If your computer doesn't have a public IPv6 IP address - you would have to turn it off on the router if it has one, some of these new home routers will tunnel Ipv6 to ipv4.


Turning off RDC won't help home users at all, this is a feature developed for DFSR, which is essential on Windows Servers. However you probably don't use it at home and it is only used by programs that specifically call for it.

just my 2 cents
