Application Profiling/Performance Optimization on HPUX

Vishwanath RN — Mon, 22 Nov 2010 09:21:11 GMT

Hi,

I got an inquiry from a customer on performance tuning of a C++ application on HP-UX. Could anyone here point to some of the profiling tools (for monitoring performance at class, method levels) and identify performance bottlenecks within the code?

Regards,
Vishwa

If this is Integrity, there is caliper. At the system level, there is glance.

And to a lesser degree, tusc might be considered a tool for tuning by showing if there are ecessive or redundant system calls being made.

the best profiler and debugging tool for c/c++ is valgrind.

http://valgrind.org/info/tools.html#cachegrind

don't use it on production though, because it realy slows down your application when profiling, but you do get a lot of info from it. ideal during the development phase!

Dirk - valgrind et al are quite nice, I've used them from time to time with netperf. However, since the context is HP-UX, and there is (to my knowledge) no HP-UX port (PA-RISC or Itanium) of valgrind, it won't help Vishwanath all that much :)

hmm, indeed, i never use c on HPUX so i was not aware this excellent tool isn't ported.

still, it depends on how portable his C code is, could be developed on linux using valgrind and then compiled on hpux.

who knows...
