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):


How reproducible:
Always

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

Actual results:
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

Expected results:
RHEL3 should be consistently low as, and even lower than Red Hat 7.2
