Performance Issue (Bug ?)

Hi, I'm using a set of (self-written) scripts to do some db-interactions (eg. reading recordsets from a DB2 (AS/400), converting them and inserting them in a MySQL-DB). These scripts where written on my office-workstation where they run very well. When i put them on our intranet-server the script performance dropped to a point where it was not even possible to import all of the data because of the massive runtime (around 6-7 records/sec compared to 400-500 on my workstation). I did some research and stumbled across some benchmark-scripts written by Sebastian Bergmann ( http://www.sebastian-bergmann.de/PHP_Benchmark/ ) which i used to benchmark the two systems. My office-workstation: AthlonXP 2400+ / 512 / 5400rpm HDD IDE / Win2k Pro / PHP 4.3.4 Intranet Server: 2x 2.8GHz Xeon / 2048 / 5x 15.000rpm Raid5 / WinNT4 Server-SP6a / PHP 4.3.4 Nearly the same php.ini is used on both systems (except for error-reporting and stuff like that). One should expect to see all of the above tests run faster on the server. That is true for all but one test: No5 (Array Index Access) shows terrible results (~740.000 on my workstation / ~10.000 on the server). Even if I don't use this type of access in my scripts I think it is the explanation for the terrible performance. I tried older versions of PHP and found the "bug"(?) existing since 4.1.0 No Apache was involved while the scripts where run (cmd-line). Does anyone have an idea what might cause this type of problem ? Greetings and a happy new year Jochen Boedeker
