Hi everyone,
I am not that firm in kernel configuration and the effect to the system (memory usage etc.). But reading the .config file it seems there is a lot of stuff compiled in the server kernel which is not needed?!

Again, I am no kernel wizard, but maybe this helps giving Wikipedia even more speed on the new server.
I would add to the list of features we could probably do without:
CONFIG_PM=y
does *.wikipedia.org ever go into power-saving mode? Unless it's for blanking a terminal screen attached to it, if there is one.
CONFIG_BLK_DEV_RZ1000=y
unless the host actually uses this chipset
CONFIG_BLK_DEV_PIIX=y CONFIG_PIIX_TUNING=y
I KNOW it isn't a PII or other Pentium
CONFIG_BLK_DEV_IDE_MODES=y
CONFIG_SCSI_AIC7XXX=y CONFIG_AIC7XXX_CMDS_PER_DEVICE=253 CONFIG_AIC7XXX_RESET_DELAY_MS=15000
I think this was the default SCSI controller, I know I also found SYM53C8XX added.
I would favour keeping the module support, though. Otherwise, yeah, what Thomas said.
