Running the performance suite
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To build and run the whole performance suite, run "make [--quiet] perf".
To run a subset of the regression tests, execute:
perl perf/vg_perf <name>
where <name> is a directory (all tests within will be run) or a single
.vgperf test file, or the name of a program which has a like-named .vgperf
file. Eg:
perl perf/vg_perf perf/
perl perf/vg_perf perf/bz2.vgperf
perl perf/vg_perf perf/bz2
To compare multiple versions of Valgrind, use the --vg= options multiple
times. For example, if you have two Valgrinds next to each other, one in
trunk1/ and one in trunk2/, from either trunk1/ or trunk2/ do this to
compare them on the entire suite:
perl perf/vg_perf --vg=../trunk1 --vg=../trunk2 perf/
