Review other sampling profilers

• Ease of use
• Output format

gprof: needs compiler switches, can't profile shared libraries (?)

[krlmlr]

valgrind/callgrind instruments, slows down code by factor ~50

[krlmlr]

IgProf: Linux only, otherwise similar to gperftools

RotateRight: Looks unmaintained, needs suid bit

OProfile: needs root

http://oprofile.sourceforge.net/about/

[krlmlr]

dicej/profile: looks like a much simpler version of gperftools

ptrace-sampler: Unmaintained pre-alpha

https://github.com/oliver/ptrace-sampler

[krlmlr]

rsvp: OS X only, requires root

[krlmlr]

CodeXL: Windows and Linux (but no OS X), worth a try.

https://github.com/gpuopen-tools/codexl

Ubuntu installation didn't work: Error running dpkg --configure.

Many other proprietary options, or tools that don't quite fit the scope: https://en.wikipedia.org/wiki/List_of_performance_analysis_tools

[krlmlr]

traceR: An entire framework, instrumenting profiler focusing on R. Worth a try too.

verysleepy: free, worked very well last time I checked, but may require additional work to turn into a library. Windows only, but perhaps useful in combination with gperftools.
