performance - How to profile set of process in freeBSD? -

i trying debug service respect performance. service trying debug, internally spawns instances of same binary. improve through-put, planning increment number of instances of binary. after point in number of processes of binary, through-put not increasing. trying reason-out why happening.

i need help on start, tools available process level profiling. using freebsd platform.

if using more processes doesn't improve output, service isn't cpu bound. might constrained e.g. disk or network throughput instead.

start systat. systat -vmstat. see man systat. whill show several aspects (like memory usage, interrupts, processot usage , disk activity) of how busy scheme is. if programme lot of network activity, using systat -tcp might give insight well.

if service http server, might want @ varnish.
