Could The TCP Optimiser Be Affecting My Connection?

ok got off the phone with VM and they say try to remove the TCP Optimiser.

But how do i do this?

They Say that because its for 20 MB connections it could actually reduce the speed and it does seem to be sticking at 2.2 MB download sometimes comming from 5.3 MB.

TCP optimzer is meant to help your connection but I use it on my 50Mb and I have a great reading.

I will when I get home I am at work at the moment

as you can see i hit 50 MB.

But for like 0.5 Secounds - 2 Secounds Max before it drops to 40, 30, 20 , 0.1 MB within 3 secounds...

Anyone saying to "remove" TCP optimizer is barking up the wrong tree, as TCP optimizer applies settings, removing the program itself will do nothing - not sure if there are options which would restore all settings to default.

For Vista, it is better to allow the TCP/IP stack self-tuning to react, using optimizers in Vista is probably wrong in most cases, but for XP, the 20Mb optimize should be better than XP default, only thing I could suggest is to find the RWIN setting in the registry and double it.

One other thing, with large RWIN, enabling timestamping tend to stabilize throughput, as RTT calculation once per RWIN is not adequate at higher levels, particularly as the delay tends to jump once the window size is ramped to the point where throughput saturates.

If you are on 50Mb and on XP then you are generally advised to run the TCP optimiser from the Speedguide website.

Hm, I'm a bit curious what the TCP optimizer actually does, as a friend of mine says you should never alter the TCP stack. Thats what the old AOL software used to do isn't it? Forcing people to reinstall windows if ever they wanted to go to a different ISP.

Could someone clarify what the TCP optimizer actually does?

It changes a couple of Windows registry keys, that's all. The AOL parasite is an entirely different thing.

I'm only on 2Mb using XP and it's made a massive difference to browsing. It's made things faster and smoother. A web page nowadays has all sort of links to ads etc which seemed to slow everything down for my system.

What value is your TCP Recieve Window configured as?

65536 is enough to support Gigabit ethernet. Make sure it's no more than that as it can have adverse effects!
Enable Window Scaling, timestamps, MTU Discovery, and select "Modify All Network Adapters".
