For source code, you probably want to look into "strace -c" or its
"ltrace" equivalent. Perf would also be an option.

If the code tends to be network related, I suggest capturing the traffic
with tcpdump and inspecting with Wireshark. The "tshark" commandline
tool also has great features like "-z rpc,srt,..." for showing the
Servise Response Time.

There is also "gluster volume top" and "gluster volume profile" you may
want to check.

HTH,
Niels
