[Freeswitch-users] TCMalloc and freeswitch

[Ali Pey]

We haven't measured the effect in Production yet, but in the lab, it made a
big difference.

The main problem that tcmalloc fixed for us was the threads locking on
malloc and calloc and killing the CPU. I strongly recommend tcmalloc. In
low traffic, it won't make a big difference, but in high traffic, you
definitely need tcmalloc.

I will provide an update when I have better measurement from our production
servers.

Regards,
Ali Pey
