APC makes a huge difference. Most hosting companies have no PHP optimizers, some might have zend which does help, but APC is in a completely different league. I've been talking to the good folks at Rochen who manage our joomla.org servers. Those are super busy servers, with something like 500 requests per second, and after I told them about APC and they installed it they LOVE it. Server loads dropped dramatically, response speed increased and basically they can handle more requests. with APC they see upwards of 99.5% cache hit, that means that only .5% of all calls are not coming right from the APC cache.
Anyway enough of that, I used to use phpwebhosting for my personal site, and while they were fast and offered ssh, and pretty much no limits, they did start to get slower, and slower and slower. With my dedicated server, I just didn't need that hassle any more.
Andy... what is APC? Do you have a informational link?
