[lttng-dev] Performance impact using the "filter" option

[Ilya Mirsky]

Hi all,

It's a simple question, but I couldn't find the answer in the documentation.
Figured out I'll ask here before looking this in the code.

Should I expect LTTng's overhead to be lower when filtering some of the
trace points,
or is the main overhead is due to the trace point call and not the
recording itself?
In practice I see no noticeable difference in performance,
while I was hoping to get at least some improvement...

Thanks,
Ilya
