apache speed problem

Hi

I use redhat9 with httpd-2.0.40-21.20.legacy,php-4.2.2-17.2 and mysql4
Lately I've compiled latest version of httpd 2.0.55 with php 4.4.0. I've
used the same configure line for php and httpd as previous version.
My redhat9 has two working version of apache in
/etc/httpd
and
/usr/local/apach2
If I start httpd-2.0.55 and open any php pages fg phpinfo.php I see
significant difference in speed.
I've tried also phpcgi with mod_fcgid and php generation time seems to work
faster but viewing pages is still slow.
Pages open line by line with 2.0.55. The same page opens in no time with
2.0.40
Any idea what is wrong?
