I can only say: not much. It initially helped a bit but as soon as
I'm starting compiling (first glibc, then mozilla) all the memory is
again wasted^h^h^h^h^h^hspent on caches. The following is during the
mozilla compilation:

        total: used: free: shared: buffers: cached:
Mem: 523837440 517189632 6647808 0 21442560 441991168
Swap: 402096128 126083072 276013056
MemTotal: 511560 kB
MemFree: 6492 kB
MemShared: 0 kB
Buffers: 20940 kB
Cached: 431632 kB
HighTotal: 0 kB
HighFree: 0 kB
LowTotal: 511560 kB
LowFree: 6492 kB
SwapTotal: 392672 kB
SwapFree: 269544 kB

At the same time I'm writing in XEmacs and have often no feedback on
keypresses for some seconds. The cache buffers still take over the
whole VM.
