[Freeswitch-users] performance between bridged call and conference

[Anthony Minessale]

Mac indeed has some unfair hard-coded 2500 thread limit that we can't
explain, we've seen it all along.

Don't trust the load avg on linux when you have lots of rtp, it's not
real its thrown off because of all the rtp traffic causing scheduler
wait.

anyway, you learned the limits of your box for yourself, good job!
That's what I like to see.

naturally, you get better or worse results depending on how many cpu
you have or how fast each one is.
