[Freeswitch-users] Huge CPU LOAD increase between 1.4.12 and 1.4.14

[Dmitry Sytchev]

So, have you solved your problem? Did you change rtp-timer-name?
After we moved to 64-bit system, 1.4 branch shows huge LA spikes up to 35
on 4-core (or 4 single core virtual processor) with only 200-300 concurrent
channels and very low CPS (1-5).  On the same call load LA of 1.2 server is
significantly lower.
Setting 1.4 64bit to normal priority with -np helps to lower LA, but not
completely solves a problem.
It shows very big values in "ni" top fields (20-30%), but changing nice
value of FS process to zero or positive value doesn't help.
