It sounds like PHP is the culprit.

PHP is slower than molassis on a winter day. Not sure how they compare
but Slashcode will be alot quicker (IIRC, alot of pages are written
statically).

You're also doing alot on that box.

A faster connection will help but theres other issues at play if a
100k/pg takes 15sec to download.

More information such as load averages, memory usage, network stats etc
would make finding the culprit easier.
