For a couple of weeks I have been bitching to my friends on Mark Minasi’s forum that Vista SP1 file copy across my network, especially to my Windows Home Server, was slow. By slow I mean 200K per second, I could download faster than that!
Mark suggested to me that I play around with the TCP settings, and sure enough I am now getting rocket speeds across my network. Mark also pointed out that I really should have known this as an administrator of his forums… why…. well, it was in his last newsletter which I forgot to read… ooops 
You should read that edition of the newsletter for the settings you can try and the reasons these settings are needed.
Whilst you are there, make sure to sign up to the newsletters!
Exactly what did you do? Read the newsletter you referenced and it only seemed to apply to settings you should make for very old routers.
Hi JML,
I set to =disable, and yes… it seems to only apply to old routers, not in my case.
I have dell Managed switches, less than a year old, with the latest firmwares, and this made a huge difference.
Thanks Nick. Really enjoy your blog.
Why… Thanks! 🙂
