Cholla, I think my english is not very good, but your spanish is a little worse... It is a joke !! My wife is telling me that someone or something is getting out of my PC and taking me in... And perhaps she is right. I am getting crazy. I have tested so much settings combinations that I don't know which to choose. But it's true that my beginning connection didn't work and now it's one of the best according to my connection. And I due to you specially and all people has helped me (dlewsi23 and Vanburen). You have devoted (perhaps even wasted) to me and my madness a lot of time and I want to be thankful for it. All the forum members are fantastic and welcomed warmly. Thanks to everybody. Perhaps I will try more settings with you links... jajajajajajajaa

I thought something as you have explained. In fact, I have made some tests with multiples of 4096 for DefaultSendWindow. I have currently 393216 (96 x 4096). I have tested with 262144 (64 x 4096) and 360448 (88 x 4096). But I am really disappointed with the results because they are contradictories with all the tests we have made before. I really think that the connection is good tweacked but it depends on the moment we do the test. It's not the same now than in 3 minutes or 5 minutes. I should have 3 equals PCs with 3 internet connections and make the tests at the same moment to be able to compare the results consistently. The phone lines vary a lot in the time (in minutes). What I think is that good values are: DefaultReceiveWindow = 524288 TcpWindowSize = 513920 GlobalMaxTcpWindowSize = 513920 (All above had been written 2 hours before). Now, I have made more than 100 test (really true). I am crazy, I know... jajaja I have tested all kind of combinations with buffers (x 1, x 10 and x 100) and DefaultSendWindow (393216, 360448, 262144 and even I have tested lower values: 16384, 32768 and tested again 65536). I have obtanied best results with buffers x 100 and DefaultSendWindow = 65536. Yes!! 65536 (downloads = 6.33, 5.59, 5.06, 4.18, 2.63 and 6.22). I don't understand anything. The thing is that a value of 393216 seems to be very large, but it was giving good results, at least in that moment. But now the best results are for 65536. If I do test at this moment I obtain bad results for 65536. I don't know what to do. What logic can I apply?

First of all, thanks to you. I am only testing your suggestions because you are trying to help me, so thanks to you again. After reading your last post, I am going to tell you what I have understood because as you were told my english is not so good as I would like: 1. You recommeds me to set back DefaultSendWindow to 393216. Perhaps I can try to reduce a little its value, but how do I reduce it? As a percentage or as a multiple of some figure or do I have to do any calculation involving several variables? Can you tell me something about it? Anyway, one of the first changes we did was to set DefaultSendWindow to 8192 (one of the Microsoft default value) and it didn't work very bad, isn't it? Notice that all the changes we have made to this value (DefaultSendWindow) have been paralell to the DefaultReceiveWindow. Perhaps we should have set first the "send" one to a small value and we should have setted up little by little. Thai is to say, instead of coming back to 393216 as now, we can go back to 8192 and setting up little by little. Or do you think it isn't good? 2. With respect to Buffers, I have them now multiplied by 100. The Microsoft default values evidently doesn't work. I will try to set them multiplied by 10. I will look for something to read in internet. Have you asked Vanburen why he sets them multiplied by 100 or what is the valid range for the buffers? Perhaps he knows something and can give us a skillful lesson!! Anyway, what do the buffers affect to? Download, upload or both? I will do several tests this night (for me) and paste the results.

I have set these to previous parameters: DefaultReceiveWindow = 524288 TcpWindowSize = 513920 GlobalMaxTcpWindowSize= 513920 These ones are now: DefaultSendWindow = 393216 LargeBufferSize = 819200 MediumBufferSize= 150400 SmallBufferSize= 12800 I have repeated the tests with above parameters so that we can compare: [glow=red,2,300]Download Stats[/glow] Download Connection is:: 4003 Kbps about 4 Mbps (tested with 20972 kB) Download Speed is:: 489 kB/s Tested From:: http://s2.testmy.net Test Time:: 2006/08/18 - 5:55am Bottom Line:: 70X faster than 56K 1MB Download in 2.09 sec Tested from a 20972 kB file and took 42.922 seconds to complete Download Diagnosis:: Looks Great : 6.83 % faster than the average for host (54.81) D-Validation Link:: https://testmy.net/stats/id-G15F86OR9'>https://testmy.net/stats/id-G15F86OR9 User Agent:: Mozilla/4.0 (compatible;

With large files even with medium sized files the tests stayed for a long time. These Microsfot default values are oblviously wrong. MrProper

yes, i had restarted my pc after changes

I paste you the results of downloading a 202 Mb file. First with current parameters (flashget1.jpg) and afterwards with the previous ones (flashget2.jpg). As you can see I get very similar results in direct downloads. I will be near my PC in case you answer me.

Before clearing current values I will download two large files simultaneously with Flashget. I will go back to previous values and I will do it again and compare. Afterwards you can fine my connection a bit more if you think it is possible. I am working now, so I will do it in two or three hours. See you later. By the way, don't you use MSN, Sonork or any messenger program? I think it would be easier at this moment to communicate in this way (we are changing constantly values and we would need sometimes a real time communication). MrProper

I only asked because I thought the parameters that determined RWIN were exclusively two: TcpWindowSize and GlobalMaxTcpWindowSize. I knew that the other one (DefaultReceiveWindow) was involved in download speed and it should be as high as possible but without fragmenting the packets. DefaultSendWindow parameter is involved in upload speed (the same as DefaultReceiveWindow but with upload speed) but is involved indirectly in download speed (because a wrong value - too high or too low - slows down your downloads). That is what I thought after reading a lot, and you must be aware that I din't know anything before coming to testmy.net. So I am learning very much and I am very grateful for teaching me so much.

Ok, I am working now (it's 12:10 p.m.) but when arriving at home I will apply the new values. It is a pity. I would have liked to continue yesterday, because today results might be different (the line might be slower or more quickly today than yesterday) so it would have been more interesting to have done it the same day. But I was very tired and I hardly sleeped today. One thing, why do you change all four values at the same time? Why don't you leave constant two values and change the other two? MrProper

Cholla, we'll continue tomorrow. Here in Spain it's 3:41 a.m. and I have to get up al 7:30 a.m. I am dead !! Tomorrow I will be here to continue with changes. But the thing is going on !! Than you. See you tomorrow.

I copy you part of the test of TCP Analyzer because it doesn't read vere well. Default TCP Receive Window (RWIN) = 65536 RWIN Scaling (RFC1323) = 1 bits (scale factor of 2) Unscaled TCP Receive Window = 32768 RWIN is not fully optimized (even though it is a comparatively large number). The unscaled RWIN value is lower than it should be. Also, RWIN being close to and above 65535 does not justify the header overhead of enabling TCP 1323 Options. You might want to use one of the recommended RWIN values below. For optimum performance, consider changing RWIN to a multiple of MSS. Other RWIN values that might work well with your current MTU/MSS: 513920 (MSS x 44 * scale factor of 256960 (MSS x 44 * scale factor of 4) 128480 (MSS x 44 * scale factor of 2) 64240 (MSS x 44)

I have made all your changes, rebooted and made tcp analizer test. I paste you this last screen so that you can see the recommendations they do. I have cleared cache at each speed test. I paste you the results for a 7,3 Mb file (twice) and for a 20,5 Mb file (once). The tests have been made against a server in USA. If I should do them against another one closer to me, let me know. Very bad results. Perhaps the server is very busy or your local time or my local time is busy. [glow=red,2,300]7,3 Mb file[/glow] :::..

But you are totally right. Have you read all the posts? I have only changed 2 parameters !! But I think I can change more. I am waiting for cholla who told me to change some values more. I don't dare to do it on my own. I prefer his instructions although your help and ideas are welcome !! What is your opinion? Do you agrre with cholla or do you have your own (and different ideas)?

Anyway, I am looking at the results of TCP Optimizer and I can see that TCP Window is limiting speed. "Bandwidth * delay product (Note this is not a speed test): Your TCP Window limits you to: 5139.2 kbps (642.4 KBytes/s) @ 200ms Your TCP Window limits you to: 2055.68 kbps (256.96 KBytes/s) @ 500ms" Assuming a normal delay of 200 ms, my top speed is 5 Mb, so I think it's normal that I can't get speeds > 4,5 Mb, isn't it? Perhaps the solution is modifying the other values you mentioned in you post (mainly RWIN).

Cholla, I am disappointed .. Repeating testmy.net test it selects automatically a 2992 KB file (instead of a 5983 KB) and my constant download speed is 2,7-2,8 Mbps. There are fluctuations in speed line... Fucking ISP !! (sorry).

Cholla, the things are improving at least at this time. I have only changed the first two parameter you told me. I have set both DefaultReceiveWindow and DefaultSendWindow to 8192 as you seggested. I have repeated the speed test 5 times. I have achieved a constant download speed of 4,55 Mbps. These are the [glow=red,2,300]results for a sized 5.983 KB file [/glow] (the test automatically selects this file to do the test): Download Connection is:: 4540 Kbps about 4.54 Mbps (tested with 5983 kB) Download Speed is:: 554 kB/s Download Diagnosis:: Awesome! 20% + : 84.4 % faster than the average for host (189.159) Download Connection is:: 4546 Kbps about 4.55 Mbps (tested with 5983 kB) Download Speed is:: 555 kB/s Download Diagnosis:: Awesome! 20% + : 76.41 % faster than the average for host (189.159) Download Connection is:: 4553 Kbps about 4.55 Mbps (tested with 5983 kB) Download Speed is:: 556 kB/s Download Diagnosis:: Awesome! 20% + : 69.82 % faster than the average for host (189.159) Download Connection is:: 4546 Kbps about 4.55 Mbps (tested with 5983 kB) Download Speed is:: 555 kB/s Download Diagnosis:: Awesome! 20% + : 63.82 % faster than the average for host (189.159) Download Connection is:: 4546 Kbps about 4.55 Mbps (tested with 5983 kB) Download Speed is:: 555 kB/s Download Diagnosis:: Awesome! 20% + : 59.01 % faster than the average for host (189.159) Vanburen gave me the other day a link to do the [glow=red,2,300]test with a 20.972 KB sized file[/glow].
