I currently use MyISAM on an internal web application server; our data takes up 10mb at this time, though this is likely to grow substantially in the coming year. The database sees moderate heavy read and moderate write usage from 50 users.
We're upgrading our sever from Red Hat 7.3 to SuSE Linux Enterprise 9.0 soon and have considered migrating to InnoDB as part of our upgrade. I like the performance increases I've seen documented here http://www.innodb.com/bench.php, though I'm not sure our environment calls for InnoDB. Thoughts?
