I think for Asterisk the performance of the FPU is the most
significant. Is price a factor for you?
Processing performance (and price) aside, the Pentium M
chip scores points because of it's awesome power consumption numbers (low),
which means it will run more quietly, more cool, and very possibly have a longer
life expectancy as a result. This is very valuable - I don't trust those nasty
fans they ship with the current crop of regular P4s. Give me solid state, or as
close as can be had.
Check out some of the benchmarking sites like
tomshardware.com and anandtech.com and look at how those two chips perform
againast each other during heavy gaming. It's a bit of an unscientific method,
but game performance is also FPU intensive, so those benchmarks would be
relevant.
Having said all that, the general consensus in the Asterisk
community suggests that you never try to see what the limits are for a
production system. If CPU load goes above 50% for any signifigant percentage of
normal operation, it's probably time to start planning for your next platform
upgrade. In other words, plan from the beginning to add servers as you grow, not
see how many concurrent channels you can coax out of the current
system.

Subject: [Astlinux-users] Processor question - MHz, FSB, or cache?Hi all,I'm in the planning stages of an ASTLinux deployment, and have a question regarding processor choice. What is the most important attribute in the processor - raw speed, bus speed, or cache? Specifically, I am looking at a P4 2.8GHz 512K L2 vs. a P4M 1.6GHz 2M L2. Both are 533 FSB. This is for a relatively small installation (6-8 Grandstream 2000, 2 500 sets, 3-4 POTS incoming) now, but eventually I expect it to grow, so I'm asking more in general than this specific case. Many thanks for any suggestions,Clint
