Confused about Memory Usage
I'm confused about RAM sizing. I have 4 couchbase servers with 2Gigs ram on each of them. I have setup 2 couchbase buckets each with 200MB PER NODE RAM and 1 memcached bucket each with 150MB Per Node RAM. So, I would think that the usage for one server would not exceed (200 + 200 +150) = 550MB. But, it's more than double that. On one server if I checkout TOP, I see memcached using 463MB and beam.smp using 584MB. Why would this be?
