[asterisk-users] call file concurrency

[Danny Nicholas]

Here is a link to a better, but possibly dangerous answer.

http://www.netadmintools.com/art295.html

Since a typical linux box probably allows about 250K files to be
simultaneously open, and you need about 2K for system and * overhead, by
cutting the max number of files down to about 3K, you would limit the number
of calls to about 1K, assuming that each open call is one file handle.

Which one?

 	-fs::sedwards:~$ ulimit -a
 	core file size          (blocks, -c) 0
 	data seg size           (kbytes, -d) unlimited
 	file size               (blocks, -f) unlimited
 	pending signals                 (-i) 1024
 	max locked memory       (kbytes, -l) 32
 	max memory size         (kbytes, -m) unlimited
 	open files                      (-n) 1024
 	pipe size            (512 bytes, -p) 8
 	POSIX message queues     (bytes, -q) 819200
 	stack size              (kbytes, -s) 10240
 	cpu time               (seconds, -t) unlimited
 	max user processes              (-u) 16114
 	virtual memory          (kbytes, -v) unlimited
 	file locks                      (-x) unlimited

Limiting the number of open files or file locks would not have the 
intended effect.

Thanks in advance,
