Jay,

Could be any number of things but check the basics and run "top" to see
if you have some processes that is consuming resources on you.   A very
easy thing to miss when upgrading from 2.4 to 2.6 is your hard disk
parameters (see hdparm command).   The unit of measurement for the read
ahead parameter has changed from blocks to bytes.  Therefore if your
current readahead value is 8 you should change it to 4096 for 2.6 although
256 or 512 may well offer the same or even better results.  Experimenting
a bit will find the best value for your drive/workload.
