All, in a class the instructor recommended setting it at 129 for
Windows.

Justin,

I believe the default is 32k. We try to get as many of our clients to
512k
as possible. I don't have any definitive numbers for you other than
"it's
noticeably faster" and also that "switch cpu usage dropped noticeably".
Our network is most certainly different than yours so YMMV.

I would try upping a few of the ones you can test on and see what
happens.

The default is either 16 KiB or 32 KiB, I was wondering if anyone tested
various sizes such as 64,128,256,512,1024 KiB and how that had an impact
on performnace?  I believe in the tuning doc they recommend you set it
to
128 KiB..

Justin.
