In our development environment, we currently use:
- gcc with every possible warning turned on (-Wall is not enough)
- gprof for function level profiling
- dmalloc for memory leak detection
- valgrind (doesn't work on FreeBSD-64 though)
- cachegrind (part of valgrind) for cache hit/miss profiling

Kprof -- http://kprof.sourceforge.net/
There are probably others too.

Hi
I am using FreeBSD 6.0. My course assignment required me to
increase process number running on a system.
I have already modify /boot/loader.conf on following parameters
kern.maxusers =3D 384
kern.maxproc =3D 50000
kern.maxprocperuid =3D 50000
But after reboot maxproc and maxprocperuid is only 5278 and 4755
respectively. From my research maxproc is calculated from maxusers,
but i think my maxproc number is limited by other factors as well.
Are there any suggestion to this problem without increasing RAM?
My system is running on VMware and 256 MB of RAM available. The test
program create process by using fork() and child processes is put to
sleep() immediately after its creation.
Thanks
