[SGVLUG] Linux time profiling tools?

Hi folks,
I'm performing speed optimization and parallelization on a complex
130k line C++ numerical code base.

What good and bad experience have people had with time profiling and
analysis software for Linux?

I am currently evaluating Zoom by RotateRight, which is $700 per seat.
 It is great.  It uses oprofile or its own kernel plugin, provides
call trees and source and assembly highlighting based on times
(screenshot attached).

The complexity of the code base goes beyond gprof (or at least the
visualization tools for it I can find).  My code is intensely
numerical and memory intensive and probably is not practical to run
under valgrind.  I see it mentioned online that Kcachegrind can be
used to visualize oprofile output, but has anyone tried it?

Any other products, free or commercial, that I'm missing?

thanks,
- -braddock
