Operating system: Windows 2000 AS / SP2
PHP version:      4.3.0
PHP Bug Type:     Performance problem
Bug description:  Parsing many include files on dual processor machines is very slow

processing include files with include_once ( these files containing classes
only in our case ) takes huge amounts of time on dual processor machines.

On a single processor machine (1ghz) the 30 include files are processed in
about 0.2sec and on the dual processor machine (2*1ghz) it takes about
3.5sec. Using only include statements (not include_once) brought
processing time down to 1.7sec which is still far from the 0.2sec on the
UP machine.

operating system: win2000as (sp2)
webserver: iis
php: 4.2.3 and 4.3.0 (maybe earlier also) standard win32-zip from php.net
with extensions gd and oci8 enabled

i've already looked through zend_execute.c but the only time consuming
thing i saw was zend_fopen().

if you need further information contact me any time.
