Hi Aken, thanks for your reply.
I'm caching menus and breadcrumbs — and other stuff also — because, in my application (custom CMS), they generate several SQL queries on every page. As these "views" won't change very often, I thought it was a good idea to store them in static files.
But if accessing static files slows down CPU and hard disks, I was wondering what was the best solution between SQL queries vs. accessing hard disk...
Anyway, my system works also with APC user cache, so the file-based caching would only be a fallback for servers where APC is not available.
