[Valgrind-developers] performances of trunk compared to 3.8.1 ?

[Philippe W. <phi...@sk...>]

At least on x86 (old pentium, and on gcc20), I observe some
performance regression (e.g. on perf/bz2) between valgrind 3.8.1
and trunk.
Also, I have the feeling that regression tests are slower.

Does anybody share such feelings ?

And better, some measurements e.g. on mips or s390 or arm,
as I have no access (anymore) to such platforms ?

e.g. assuming you have a trunk and a 3.8.1 build, you could do
   perl perf/vg_perf --vg=../trunk --vg=../3.8.1 --reps=5 perf

(even if these perf tests are somewhat not very reliable)
