Who is most garbage collected?

[Alexander Petrovsky]

Hello!

I wonder, what is the best way to find out the "culprit" of GC:

> msacc:start(1000), msacc:print().
        Thread      aux check_io emulator       gc    other     port    sleep
...
 scheduler( 1)    1.68%    1.12%   55.34%    9.05%    3.44%   13.91%   15.45%
 scheduler( 2)    1.53%    1.13%   55.17%    9.94%    4.76%    9.59%   17.88%
 scheduler( 3)    1.64%    1.21%   58.12%   10.88%    3.45%    8.93%   15.78%
 scheduler( 4)    1.61%    1.29%   57.22%   11.80%    3.97%    8.42%   15.69%
...

Using erlang:trace ang catch garbage_collection events? Or
erlang:system_monitor with long_gc or maybe there are better ways?
