Hello all I'm a new user of freeswitch and I've a few questions, 1. I've searched the mail list and some forums about the switch "waste" and I haven't found out what it does and how it does it. Anyone care to explain a little bit about it? The only thing that I've found is that it consumes more memory but in my tests [1] it doesn't change that much. 2. Do any of you guys have a rough estimate of what each call memory footprint should be? 3. About the ulimit -s 240, I've read that it limits the stack size, but I'm at a lost point as how to pick a suitable value. What is the criteria? 4. Are the tests that I've done [1] reasonable? I'm trying to know this things because I'm planning to use FreeSWITCH on a resource limited hardware. Best Regards Javier [1] test done with SIPp, using 0 to 20 users calling simultaneously, connecting the call, and hanging up after 5 secs. statistics using linear interpolation. using debian's init script (ulimit -s 240): slope 898.7 kB y-intercept 15410 kB using /usr/local/freeswitch/bin/freeswitch -waste -nc slope 810.6 kB y-intercept 16273 kB
