I am trying out Ubuntu and not that FB is a lot slower on it compared to
Win 7. I am running this on the same hardware by dual booting and
actually running FB 2.5 in a Win 7 VM under Ubuntu is just about as fast
as in native Win 7.

I am pretty sure it has to do with my setup on Ubuntu - I am very NOOB
on this.

I installed FB 2.5-super using Synaptic and didn't tune anything.

I am using Python/wxPython/sqlalchemy and the slow performance I see
when I do bulk stuff, i.e. reading from a table check in another table
if row exists and then either insert or update.

I am aware that this is a very little information, but for the moment I
am just looking for tips on what one should look at first before I dig
in further down into the issue.

BTW, the db is just copied over from Windows - is this a no no? I.e.
should I have to backup/restore instead?
