Alex and Rob, Thanks for the replies.
It looks like the "buffers" value shown by "free" on SLES is the the sum of the "Cached" and "SReclaimable" values from /proc/meminfo/, while on RHEL it is just "Cached". On SLES: # egrep '^Cached|^SRe' /proc/meminfo;free Cached: 130336 kB SReclaimable: 17576 kB total used free shared buffers cached Mem: 1020416 318156 702260 0 11688 147912 ... On RHEL: # egrep '^Cached|^SRe' /proc/meminfo;free Cached: 36668 kB SReclaimable: 25828 kB total used free shared buffers cached Mem: 245772 234828 10944 0 95568 36668 ...
