HEAP PROFILER

1) Link your executable with -ltcmalloc
2) Run your executable with the HEAPPROFILE environment var set:
     $ export HEAPPROFILE=/tmp/heapprof <path/to/binary> [binary args]
3) Run pprof to analyze the heap usage
     $ pprof <path/to/binary> /tmp/heapprof.0045.heap  # run 'ls' to see options
     $ pprof --gv <path/to/binary> /tmp/heapprof.0045.heap

CPU PROFILER

1) Link your executable with -lprofiler
2) Run your executable with the CPUPROFILE environment var set:
     $ export CPUPROFILE=/tmp/prof.out <path/to/binary> [binary args]
3) Run pprof to analyze the CPU usage
     $ pprof <path/to/binary> /tmp/prof.out      # -pg-like text output
     $ pprof --gv <path/to/binary> /tmp/prof.out # really cool graphical output
