On GNU/Linux, you wrote on IRC.

There has been a private discussion among Lire developers, ( Message-ID:
<4136DEB9.3000709 at nlnet.nl>, Date: Thu, 02 Sep 2004 10:50:01 +0200 )
about Lire performance.  It's believed the bottleneck is in the dfl2xml
phase, and performance might be strongly related to the specific
subreports used.  So, you might gain a lot by disabling some subreports
you're not interested in anyway.

I remember there is some setting, to toggle between disk- and
memory-consumption.  Wytze, Francis: is this toggle removed in some
previous release?

Furthermore, it _might_ be 150MB log needs 500MB memory.  I hope others
will join this discussion...
