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
