It's way better than my machine, but then I've not stress-tested it for
more than a few hours at stroke. But if your pages get very complex,
load goes up. But if your pages uses lots of style elements, you really
do want mmp+apc.

That depends. With mod_midgard, the entire page exists in memory * 2
during execution, since we have to pre-parse the entire page to rework
te midgard-specific stuff to plain PHP (since we can't touch the engine
like we used to in PHP3). With mod_midgard-preparser, the initial
preparsing is done once and stored to disk until the page or its
dependants change, so you save the memory and effort of preparsing
for each single request. It's not a full 100% benefit, since the preparser
only handles page/style elements, not snippets, nor page/style elements
contained in an eval. But for a typical site, all the layout work
is preparsed, and that can be a win. Add APC to that, and most
of your page could be ready-to-execute.
