The EXPLAIN really should not do much I/O. I doubt it has anything to do
with fragmentation, so I doubt this is going to help.
Actually I was referring to this in the context of addressing main
underlying performance issue, not EXPLAIN. Sorry, I may not have
communicated it correctly.
Even strance does not seem to be installed.
The filesytem type it shows to me ext3.
Thanks.
