Everytime someone asks this , the resounding answer is use a 64bit os..
No question

Hey Giovanni,
thanks for the tip... indeed the db files were heavily used
regardless if i started freeswitch with nosql option (freeswitch -
nosql)... FS was not writing anything into that files ... instead it
was just accessing it....
This behaviour leads to a waste of 40% CPU time... waiting for other
processes (mainly disk access) to finish!!!
I moved freeswitch/db/ to a ramdisk and the performance got a boost
to 140 CPS with a CPU load of 80%. I was keeping the machine for a
while (20 - 30 minutes) on that rate when i sow CPU suddenly went to
100% and FS becoming irresponsive :).
What can be wrong?
What are the limits in CPU usage (50%, 60%, 70%, 80%...) we should
not cross?
What fine tuning do we need in order to asure a long high load run?
Also, I'm running 32-bit OS (debian 5) on a 64 bit CPU... does it
have sense to move my OS to 64 bit? ... will FS gain more
preformance ?... I mean will FS perofomr drastically better 20%+ ?

Maybe your load comes from disk access?
Try putting the sql and log directories on a ramdisk.
