Hi Jeremy,

My follow-up for this answer from the other list was:

----------------
Does replication hurt MyISAM performance in the same way? If I'm running a
master that takes all the inserts and one or more slaves to take all the
select queries, would it be better implemented in MyISAM or InnoDB? I don't
need the transaction ability of InnoDB, but if concurrent replication
affects MyISAM performance in the same way as concurrent insert/select ops,
it makes me wonder which table type I should use on my high insert activity
tables. My assumption was MyISAM, but I'm not so sure now...
----------------

I may have posted the same question here, earlier. I'd appreciate any input.

Thanks,
--jeff
