When it comes to the large file serving then the OS sendfile

There is also some other advanced features like
Thread per request processing model, and much faster
OpenSSL compared to JSSE.
I have a presentation from ApacheCon EU 2007
that has some performance figures:

Which is all cool.
If you have to support lots of different platforms, though, APR seems to
be hassle than its worth -- especially given that I already need Apache
for load balancing. Pure Java is really, really nice if you're in this
boat.
That's not knocking APR -- just wishing we'd get the whole problem
licked really well in Java and wouldn't have to deal with native code
messes (like building/linking on AIX or learning enough about Apache's
guts to make substantive patches).
