I'm curious about solutions that don't require installing something on the
server side, since that's not usually an option with shared web hosting and
all.
Since PHP runs on the server, as part of the webserver, I think it
will be inevitable that you'll need to install something on your

Well, across the sites that are on our server at the moment we are
seeing an average increase in PHP execution speed of 244% (I just ran a
test). According to Zend if everyone of our clients were to use partial
page caching and the like, we'd be seeing closer to a 1000% (10x)
speedup.
It doesn't sound like you've testing to see where the bottleneck is. I
would first recommend inserting some microtime() commands into you PHP
code, like around your queries and blocks of PHP code. This will tell
you what is taking the longest time and will point you in the right
direction.
