I uploaded the ejabberd log file with all of the timing sample statements
here: http://www.mediafire.com/file/ztzlmmekhmh/ejabberd.log

 

I wrote a simple script to extract and print out all of the sample times:

Here are all the ejabberd files I've modified to add the timing samples:

Here are the modified mnesia files with timing samples:

I'm going to try compiling ejabberd with HiPE and see if that changes
anything.  I'll also try running ejabberd (normal and HiPE) on Erlang R14A.

 

Cheers,

Karthik
