i've attached the latest version of the pagecache scalability patch, updated to 2.4.10. The patch, (original version written by David Miller, current version maintained/fixed by me), splits up the pagecache_lock into finegrained per-hashlist locks, and per-mapping (~per-inode) pagelist locks. With this patch applied, bigger NUMA systems show much better pagecache scalability - but bigger SMP systems benefit from it as well.
The patch can also be downloaded from, and future versions will be available at:
http://redhat.com/~mingo/smp-pagecache-patches/
(this version is lightly tested.)
