I keep hearing about how aligning XXX on XX boundaries (or similar)
gives huge performance increases etc..
Where's a good place to start finding out about these techniques?

Uhh... it seems to be totally unrelated to
anything... just some
spurious cache problem, sometimes, if the code is executed in a
particular order, the memory layout is beneficial, sometimes it is not.
dlopen seems to have nothing to do with it. I just have to live with
it...
Yeah, I've seen this. If you look around on the web there is some code for
cache aligning in x86's - I've never tried it though.
In the last plugin I was writing I got a huge perfomance increase by
increasing the size of a ringbuffer, of course that was only in one host.
