Slow Vista Networking - an answer?

[GlenR]

Many people have noticed Vista networking seems much slower than XP's. I stumbled across this blog (and a few others) that offered a solution.

It all boils down to Vista trying to be too smart and a feature called auto-tuning is enabled that tries to negotiate over-size TCP packets. The problem is, most switches and routers don't recognise auto-tune and drop the SYN packets it uses, causing time outs.

The blog covers it fairly well and gives a command line method to turn off the auto-tuning that causes the problem. I haven't tested yet - I was going to until I found that the rig was recording from now until about 10PM tonight, but I'll give it a go then and see how it affects thumbnail browsing from my server.

I'll report back, of course, but if anyone wants to try now and let us know - feel free.

Trying to fix Vista problems from outside of Vista? Interesting.
It seems that 2008 server is free of these problems, but based on the same kernel.
I am running 2008 server as my home server, and transfers are very good, no different than 2003 server or XP.

Pretty sure I posted this in answer to your question yesterday:

Here's some interesting info on Vista and it's auto TCP window tuning feature... Turning it off could speed things up!

How embarassment! I was reading through the other links you posted and completely missed even seeing that one, arkay. I tripped over this one just searching around.

Man! Do I feel like an idiot now...



Apologies for not reading your informative and helpful replies fully.
