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.

sorry for posting twice

Have you done any tests using the CLI binary?
(to rule out the IIS factor)
