[zeromq-dev] profiling czmq applications

[Stefan Kaes]

Hi,

I’ve tried using gperftools to profile a czmq application, with no immediate success.

Gperftools use interval timers to record stack information and this seems to interrupt zpollers.

After to patching czmq to ignore errors in zloop_start(), I was able to profile. But the patch is really a brute force hack.

My questions:

Is this a known problem and are there ways to mitigate it?

Or are you using different profiling tools which work better than gperftools?

Regards,
