Finally, I got a fix for a bunch of slowdowns I’d been seeing - turns out Vista has something called “Receive Window Auto-Tuning.”

This is really smart - except most hardware out there is still dumb. As soon as I found this site and followed the directions, I was in like Flynn.

Make sure you’re running as an Administrator (can open a command window as Administrator) and execute the following command at the prompt:

“netsh interface tcp set global autotuning=disabled”

Changing “disabled” to “normal” will re-enable this setting, should you want to turn it back on again. The following command will list the status of the current TCP settings:

“netsh interface tcp show global”
