I work for a company that has several drupal (5.x) sites that get ~1million page views per month. We run memcache (for other non-drupal purposes) and I recently installed the memcache module on a few of the drupal sites. I notice that we have 2 memcache servers each with only 1 bin of 16 gigs each. My understanding is that it's more efficient to run smaller, more specialized bins so I'm trying to get the sys ops people to bust up the memcache servers into smaller bins. Is this correct? Does anyone have any hard data I can point my people to or am I misinformed and a huge catch-all bin the way to go?

Thanks,

-Drake

We did some test with 1 bin

We did some test with 1 bin versus several bins and did not notice any performance improvement. Until we started updating the website during our test.

Basically it showed that the advantage here is that when you clear a bin, you will not lose all your site's data. Just a part of it like nodes, session, taxonomy, ...
