Hi Mike,
Seeing this response to Margus' question prompted me to check my own
Interchange sever's "free" output, with the following result:
total used free shared buffers cached
Mem: 3356092 3005220 350872 0 96 2481292
-/+ buffers/cache: 523832 2832260
Swap: 8388600 18832 8369768
... which leads me to wonder about the buffers. For optimal Interchange
performance, should I be seeing more use of the buffers in conjunction
with a lower use of swaps? (I should probably note that this server is
also running a number of PHP/MySQL sites in addition to serving several
Interchange catalogs).
Thanks for your time and input,
Tom
