Hi,
I was wondering if it was possible to monitor the maximum and/or average
memory usage of a mock build process. I am trying to investigate why a
package takes less 2 hours to build on F16/F17, 24 hours on F18 and 7
hours on rawhide:

Hi,
I would like to follow up on this issue. I did not notice the
differences when mock building locally, but on the plague RPM Fusion
builder it took 2 hours on F16/F17 and 30 (sic!) on F18 to build mame.
Suspecting memory usage issue I already added
%global optflags %{optflags} -Wl,--no-keep-memory
-Wl,--reduce-memory-overheads
to the spec file. Thank you for the input in advance.
Here's one difference between F18 and earlier that does affect memory usage:

See https://bugzilla.redhat.com/show_bug.cgi?id=833311 and
/etc/rpm/macros.dwz for further info on memory consumption and tunables.
But then this is the same in rawhide and f18 so it doesn't explain why
the build takes *that* much longer on f18.
