Any thoughts on how to figure this out (disk buffer size)?  For some reason, my system (2xAMD 2800+, 2Gb RAM 2.4.21 -
/proc/meminfo)only shows a usage of  88kb of 'Buffers' usage, and that never changes.  My 'Cached' usage is 1.7Gb.
I'vehit the kernel mailing list, and the one response I got said don't worry about it :-( 

Cheers,
Rob
