Cache.ram is not "completely" useless in a multi processes. If your caching the entire html output of your front page, then its faster to have this cached in ram instead of on disk, but its not a big deal since its ok for new threads to recreate the cache in this single instance.
Also if your running on latest stable web2py code, it does include some cache statistics in appadmin, including memory usage if you have guppy heapy installed -Thadeus On Fri, Feb 26, 2010 at 7:07 AM, szimszon <[email protected]> wrote: > Nice.
