I turned my PMTU Discovery on. I haven't changed my Windowsize.

Test 1, everything @ default except for my MTU and RWIN as you can see in the adjuster.
Test 2 coming up... rebooting with new settings.

Test 2. If you pay attention to the analyzer, you will see extra settings.
Note: I am not recommending any of my current settings to anyone. It is for advanced users only. Wrongfully editing the settings I edit may cause you to format. There's your warning.

Even though the speed test says I'm faster, I'm browsing like a snail. Larger RWINs are not always the answer. BTW, it's peak hours, not exactly the right time to be testing. I usually get 1.5mbps and up
Final test coming up...

The 2nd smallest RWIN got the best score. Weird eh?
I'm done with testing for now. Later I'll try a test with the System.ini tweak.

Happy tweaking!

Here I changed my RcvWindow size to 30492. Anything higher brings down my speed right now. I tried 37752 but it was a bit too high for me. My provider says my LINE is 1.2Meg. But most only will get 900k streaming.

Notice RcvWindow limits me to: 1219.68 (1.2Meg) which is where it should be!

811k Down is the actual speed I get.

Finally. I think I've got the best Rwin so far.

Still can't any higher than that though. Sam speeds but I cut my Lag time down.

[darkreign]

EvilAjax, what about streaming media? As i understand the buffer tweaks help out more for streaming audio/video.
Is that true?
thanks

[EvilAjax]

I didn't notice a difference.

[darkreign]

thanks for the reply.
ill try it out
oh btw one more question, you dont support the super web page tweak anymore? as your maxconnections are empty. Default with WinXP is 10+10 i think(well thats how my one was :P )

[EvilAjax]

If you scroll up to the second analyzer you'll see that I do still support it.

I'm just trying things out with default values for a while. Just applied the System.ini IRQ tweak and I'm going a bit faster

Irq3=7168
System is a little more sluggish though... nothing Tweak XP can't fix! Just run the memory optimizer.... and.... voila! FASTER!

[TradeMark245]

Keep in mind the latest Worm Virus which attacked many systesm.

I believe some ISP's are still experiencing slow downs from purging their systems and the Netwrk Admins haven't tweaked them back up yet.

I haven't tested my new 811k down speed yet with some streaming media. I think I'll go watch some vids online. If you like movies I suggest this website:
