Red Hat Bugzilla – Bug 200869
gethostbyname_r() call takes more time in RHEL 3 than Red Hat 7.2
Last modified: 2007-11-30 17:07:10 EST
Description of problem:
A measure of the time taken to call gethostbyname_r() turns out that this API
takes significantly more time to return than Red Hat 7.2.
Also the recent upgrade from Red Hat 7.2 to RHEL 3 turns out that, the time
taken by gethostbyname_r() is not as stable/consistently low as previously in
Red Hat 7.2.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Get system time before calling gethostbyname_r();
2. Call gethostbyname_r();
3. Get system time after calling gethostbyname_r();
4. The time taken by gethostbyname_r() is the difference between system times
of step 3 and step 1.
It is expected to call multiple domain names under both RHEL 3 and Red Hat 7.2
It takes longer time on RHEL3 than on Red Hat 7.2. Also the time used by
gethostbyname_r() for different domain names on RHEL3 are more diverse than on
Red Hat 7.2
RHEL3 should be consistently low as, and even lower than Red Hat 7.2
