Hi, recently had to install a system in Windows. The OTRS version is 3.0.9 and I installed in a pretty basic way. Migrated data from 2.2.7 into the new version. Now I notice that the system performs worse than I expected. The system is running Windows2008 server in 32 bit, is a 3.0 Xeon dual core at 3 Ghz and has 6 Gb of ram. Each time a user logs on to OTRS or performs a more complex action the CPU load spikes to 100% and this is largely due to the httpd.exe process. I would have expected that this config would be able to run OTRS oke. I already moved files from database to filesystem, archived 35k tickets (still around 70k tickets in system), did some database optimization (larger key_buffer_size (1024m), added thread_cache_size=40, added table_open_cache = 1024) and activated the WinNT MPM with 150 threads in the httpd.conf. This seems to have no effect on performance. There are around 20 to 30 active agents on the system. - Would I be better of running IIS? - Would I be better of installing Apache under windows myself? Any help / tips are appreciated. Regards, Arnold
