Yes the old server was a Quad PII - 4 Intel 400Mhz processors, it ran like a
champ with QMT, Apache, Bind, and FreeRadius.  As soon as the Apache, Bind,
and QMT were rolled into VMWare -it became a dog.  I used about every tweak
I could find on the internet to make it work better.  I think the problem is
VMWare Server 2 - it's just slow.  Unfortunately I could not use Xen or KVM
because of the old processors.  From what I could research, they would have
worked much better.  I am pretty anxious to see how this runs on another
server with dual Intel 3.Ghz processors.  Unfortunately they aren't dual
core, but we should still see some marked improvement.

Thanks for sharing.

Before I comment on this, I want to check the facts. This was a Quad P-II,
and not a Quad P-4, right? Just checking. Not that it would make all that
much difference. I'll have some comments to make regarding your experience
with VM guests soon.

FWIW, I just migrated a QMT from one VM guest to another, on the same host.
The former ran nicely (and still does on another host). The new QMT VM is a
pig. I'm not sure what the problem is yet. Top takes 10% of the cpu on the
pig host, while on another guest w/ same kernel, top runs less than 1%. So
somewhere I'm seeing a ~10x performance difference between 2 guests on the
same host. It'll be interesting (to say the
least) to find the reason why. There are some differences between the 3
guests, but not too many. I hope to nail it soon.
