php cli is trying to resolve

[Hetz Ben Hamo]

Hi Ido,
I tried the same thing here. I tried it on 2 machines (CentOS 5.3 both
of them).

In both cases, the first time it runs the script, it takes few seconds
to "initialize" things, that takes 2-3 seconds, but after the 1st
time, everything runs real fast..

Here's the result from my production server (it's a Pentium 4 machine):

First time:
$ time php test.php
This is a test
real    0m3.547s
user    0m0.034s
sys     0m0.021s

Second time:
$ time php test.php
This is a test
real    0m0.044s
user    0m0.033s
sys     0m0.011s

I can see from the strace that it does check some config files like
nsswitch.conf and DNS issues, but nothing more..
