Slow execute RHEL5.4's malloc & free
When malloc & free executing in cyclic,
RHEL5.4 is slower (about 40times) than
RHEL4.7.
I guess malloc(glibc) thechnical enhance on RHEL5.4, so 2 environmental variables set,
but still slow..
MALLOC_ARENA_MAX=32
MALLOC_PER_THREAD=1
Anyone has any ideas what we need to faster?
Thanks

Re: Slow execute RHEL5.4's malloc & free
Today, I tested after install glibc-utils package as listed in bugzilla.
Though RHEL4.7AS is 70sec, RHEL5.4S is still 1,050sec(NOT enough).
As you said, I request it from the support of RedHat.
The result develops here.
Thanks
