App on Linux - really slow... any ideas why?

[Bernard Devlin]

There are several bugs noted in RQCC about slow performance in Linux.
Some of those marked 'fixed'
(http://quality.runrev.com/qacenter/show_bug.cgi?id=7273) are fixing
symptoms that manifest because of the much slower performance.

I found Rev 3.0 was unusable on Linux, and gave up trying.
