Of course all Perl and mod_perl performance tunning tips als apply to
Embperl. Especially helpfull is the mod_perl guide from Stas Beckmann.
Another thing you could do is using caching, either in the way Neil
described it (by using a front end proxy) or by using the build in caching
of Embperl 2.0, in which case you have much more control what and how long
things are cached. The downside of Embperl cacheing for now, is that it uses
an in memory cache, so you might need a lot of RAM. This is something that
could be improved by using some sort of disk caching, which I might
implement in 2.1.

ANother thing which I think would greatly improve performance is the use of
threads, because a lot of resources can be shared between threads and
therefore the Apache has a smaller memory foot print. Unfortunately Embperl
cannot handle threads yet, but I plan to implement it in 2.1.
