It aims to speed up your Apache webserver by caching the parsed PHP object code, in a manner I don't understand because I use neither PHP nor APC. However, there are two takeaways from those two sentences. The first is that it is a cache, the site should function without it. The second is that it is meant to speed up your webserver. If it is not doing so, and is instead causing load issues, it seems counter productive to use it.
