So it's using 900 MB of real memory. Swap is used, but the vmstat's I've seen all had very small si/so rates (0 most of the time, 5 maximum), so this is no issue.
Ok, but this is on a dual Cpu- a single one apache would run fewer threads. Would this halve Apaches's memory?
Thinking of moving more things over to memcached, 1 GB seems to be the absolute minimum to me, I'd prefer 2GB.
What exactly does memcached do? If it's caching the full page- then we have the Squids. If it caches common elements- then it won't need a lot of ram. Each page should be produced once, and then randomly-picked by any of the Apaches (especially if we move to ESI at some stage), so i don't see a lot of gain in memcached. Shure it would be faster for a single machine, but i doubt it will be faster than two small machines that cost the same.
From the above i would expect 1Gb to be really on the safe side.
