Actually, from what I understand - and in personal experience, Linux has
superior threading models than most any other OS (BeOS excluded - no one
beats its model). In linux, everything is essentially a thread. It just
depends on whether or not you want its stack and other data to be shared or
not. This is pretty different from WindowsNT in that you have both
processes and threads (and many diffrent types of threads).
Also, SMP works quite well in linux - there is no need to avoid using it.
Almost every linux server I have worked on has been SMP.....there has never
been a single incident where SMP broke something (and we are talking about
using lots of things on the same machine). This includes software RAID,
JournalingFS, apache, ftp, ipsec, and firewalling.....and a limited Oracle8i
database (limited in that it wasn't hit that hard performance-wise).
After all this linux talk, I kind of want to set up a CF box under linux
just to do some performance testing.....anyone have any good benchmarking
scripts?
Again, not dictating what people should run CF on.....just clearing up
earlier statements which I think might be slightly incorrect.

While Linux does support SMP, multi-threading, and the like that doesn't
mean that it does it very efficiently at this time. These issues have been
brought up before and have been proven by multitudes of tests. That being
said, things should improve dramatically with the 2.4 kernel. Also, many of
the things that Linux is used for it does in an efficient enough way that
SMP isn't often needed. This will have to change as businesses look for ways
to leverage Linux in ever more demanding roles. You obviously wouldn't want
to install a large Oracle db running on Linux with 1 CPU and 128MB RAM :)
Linux is not currently a platform on which you want to run heavy SMP-centric
processes. The caveat to this is if the process can be efficiently farmed
out to a cluster. In this case Linux r0x in both performance and cost
effectiveness.

Regarding Linux supporting multiple CPUs, I stand corrected and appreciate
the update. Last I had heard, the official kernel hasn't changed. The CPU
comment I made was wasn't meant imply Linux was bad, simply to say that it
is something to consider when evaluating the cost and number of servers.
Whether to use Linux, NT or Solaris really is a per-implementation solution.
There are obviously trade-offs in terms of hardware and software costs, the
cost and availability of specialists in each OS, and integration with the
enterprise to consider.
Thanks again for the information. I appreciate it.
