Cache??  Bottom

  • Hi
    What exatly is Cache?
    I had it on PostCalender, and one
    day, my site's webusage shot up from
    about 150mb to 500!!!
    I did sme experiementing
    and the cause was cache in the
    PostCalendar module, I turned it off and
    now all is ok.
    --BUT--
    I need to use PNesp, this also has cache, but
    I cant turn it off, will the same thing happen?
    What exatly is cache, i heard its something to help speed
    your site up????
  • I doubt it was the cache doing that... Caching items is like storing them in a temp folder, so to speak, so they don't have to use up resources repeatedly...as for pages that are no frequently updated, for instance. Caching allows site visitors to get served pages faster...once a page is served initially, it's then served from the cache until the cache on that particular page expires. Moral of the story: cache is a good thing in most cases.
  • Caching template output such as in PostCalendar, pnRender and Xanthia themes will actually use up a decent amount of disk space initially, but it won't continue to grow but stay stable at the same size over time. The initial jump happens as all of the template output gets cached and then stablizes once all the possible output cases are cached. From then on, the contents of the cache gets refreshed but shouldn't change significantly.

    On the other hand, jumping from 150mb to 500mb is pretty excessive. I'm not sure I would expect quite that large of a cache to be built....
