[Freeswitch-users] Tuning Up Freeswitch

Fri Apr 22 14:14:36 MSD 2011

hi

if you refer to my e-mail

yes, we do use tmpfs on both variants but
- delays occur with concurrent calls > 80-100
- cps is limited to 5-10 on debian, with centos 30 cps and more are no problem at all

also cpu load, stability and overall performace have been much better since using centos

i just found out for me that debian works not as good for me as centos does.
btw. everywhere else debian is 1st choice (desktop, lamp, db etc.)
