By the way, has anyone already tried to quantify in a *more scientific* manner the actual extra memory we should let on a box to be sure memcached won't swap ?
I guess memcached related overhead should be proportional to the expected number of connection and their traffic. I guess this is about the same for the OS with its internal buffers. But I must confess that so far, I don't know the exact multiplying factor(s) ...
