has anyone played with the securelevel variable in the kernel and the immutable flags in the ext2 file system?

I noticed that centos 5.1 seems to be swapping programs out of memory at times resulting in slowness (perceived by me). I played with swappiness (/proc/sys/vm/) setting to 10, then 1 then 0.
