Issue Summary

Thanks for this module, which looks very handy.

- I found looking for info on boosting Drupal performance, after trouble w webhost re ballooning mysql database (from cache, tho maybe not Drupal); also w Google now saying more re need for speed.

Found module page; but info sparse - rather more could help, esp someone like me who's not at all a coder/"developer", but would still like to boost performance.
For instance, a bit more re what memcache etc are: and what you need for installing (control of server, for some, it seems; for shared host as me, db and file look main options)

I've found: http://www.achieveinternet.com/blogs/apc/drupal-caching-cache-router
- inc info on using module for shared hosting.
Maybe w shared host, db cache not so good, or database may balloon.
I'm trying w filecache in sites/www.example.com/files - as have multisite install, maybe better not to have all cache files together.

Might file caching require a lot of space on server?

Wonder re Drupal caching: should I turn it off, after emptying it?

Maybe, too, enabling or disabling cacherouter via Modules admin makes no difference? - it's just the lines in settings that count.
