There have been some sluggish kernels recently because of some debugging 
code,
the latest kernel-2.6.15-1.1884_FC5 seems OK.

There have been some problems with font caching recently. I understand 
that these
should be fixed soon.

You might check your raid performance with "hdparm -Tt /dev/md0"
I'm using 4 way striping on 10Krpm SATA drives (SW RAID 0) on an X2
and I'm getting a very snappy 237MB/sec for disk reads.
RAID-1 will buy you protection against disk failure, but it doesn't
do much for performance.
