You'll find mysqldumpslow (in the mysql distribution) does all that and

FYI, people experiencing this problem should try to make the mysqld as
idle as possible (ie disconnect or idle the connections) and then run
truss -p NNN (where NNN is the pid of the mysqld process) and post
a typical chunk of the output.
That would give valuable info to the mysql developers.
I suspect the point is that many more threads simply makes the problem
appear more often and thus be reproducible and thus more easily fixed.

That would run faster if you do a prepare with placeholders outside
the loop and then just use $sth-execute($j, $j, $j) inside.
measuring the elapsed time of the perl script to do
benchmarks, as here, then it'll give a more accurate picture by
removing irrelevant overheads.
