Any kernel I've ever used has taken that much memory to run ut2004,
be it a 2.4 kernel or 2.6. Can you do a "echo 0 >
/proc/sys/vm/swappiness" to keep your machine from swapping? It works on
FC2 with 512megs of memory. Otherwise you can add some variables to your
etc/rc.d/rc.local file like :
echo 16 > /sys/block/hda/queue/max_sectors_kb
echo 0 > /proc/sys/vm/dirty_expire_centisecs
echo 0 > /proc/sys/vm/dirty_writeback_centisecs
echo 60 > /proc/sys/vm/dirty_background_ratio
echo 95 > /proc/sys/vm/dirty_ratio
All this does is tweak your virtual memory.
