PCMS is a rather obscure Synchronet acronym that stands for "Programmable Command and Menu Structure". Baja is the compiler that converts the .src (source) file into an executable binary (.bin) file that is then interpretted by Synchronet as a command shell or loadable module.

If you're familiar with Synchronet command shells or Baja modules, then you're familiar with PCMS.

Out of curiousity, I've been comparing PCMS performance to other interpretted scripting systems and the best I could do was come up with this simple (BogoMIPS inspired) bench mark code:

# PCMS Bench

int i t start

set i 0
call clock_sync
printf "Calculating Performance ..."
:loop
time t
compare start t
if_equal
add i 1
goto loop
end_if
printf "\r\n%lu addition and get-time-of-day operations per second\r\n" i

return

:clock_sync
printf "Synchronizing clock ..."
time t
:sync_loop
time start
compare start t
if_equal
goto sync_loop
end_if
crlf
return

It's very system-load dependant, to you'll want to run it when there isn't much (if anything) going on. These are the numbers I've seen so far (averages):

32000 on a lightly-loaded 700mhz Pentium III running WinNT 4.0
900 on a lightly-loaded 300mhz Pentium II running WinME
500 on a medium-loaded 300mhz Pentium II running WinME (same machine)
40000 on a lightly-loaded 200mhz Pentium I running Linux 2.2.14

Wow, huh? Let's hear it for Linux! (or maybe it's GCC that should take the credit?) I haven't tried different OSes on the same hardware yet, but this could prove interesting. Also, I haven't tried the Borland or GCC builds for Win32 to see if they get different numbers, but I suspect they would.

Oh maaaan!

You've just opened Pandora's Box.

Ok...just ran this on my computer. PII 350mhz with 224M RAM running Windows 2000 Pro.

31100 is the average. I've got Synch, EleBBS, Internet Rex, Argus, ZOC, 2 command windows, editpad, & COM/IP all running. I may right a program real fast that computes pi and see what kinda benchmarks I'll get. :)

Nah...I'll skip computing pi for now...

Man do I need to learn how to spell or what. That should have been write.
