I received an off-list reply from another user who experienced a similar
problem with new linux kernels and the syn cookie checking feature. I
posted this here to give GTA a chance to investigate. Vista has been
out for over 2 months now and I was amazed how long it took to find that
others were having these problems too. If you want to verify it,
compare IE performance vs Firefox performance hitting my site at
http://www.greenfam.org/gallery2. Anything on my server seems to be
hit even harder than the rest of the net which I can only attribute to
the fact that it is also behind a GB-Ware unit. This only affects
firefox/thunderbird/putty/etc on Vista and not on XP.
GB-Ware is not the only firewall I've had this issue with, so it is by
no means unique. The purpose of my post is to give GTA and others a
chance to test this. I have a workaround which is fine for the few test
deployments we are still doing, but as Vista is now released to the
public this has the potential to get very big quite quickly.

There's lots of other O/S's that can do RFC 1323 auto stack tuning, have
you checked that they work OK and it's not a Vista problem?

Subject: [gb-users] Apparent RFC Compliance Issue with GB Ware -
Affects
Vista Performance
http://www.ietf.org/rfc/rfc1323.txt?number=1323

auto-tuning.aspx
We've been trying to locate the source of this issue for two months
now
and it appears to come down to this feature. Disabling the feature in
Vista corrects the performance issue, however since the default is
enabled this is going to affect a large number of people very rapidly.
I would recommend that GTA look very quickly into their compliance
with
this RFC.
