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.
