Just so we're clear, what's the magic number that make a BOB into a
BLOB? In other words, what's "large" in this context?
Today a blob is first read into memory and then copied through the net
buffer (which I might add is a stupid step that needs to go away with).
If you have a thousand connections each tossing around 16meg blobs and
you have in flight all at once you better have some memory available.
Memcached by default limits you to 1meg per serialized object. This
seems small, but when you start thinking about concurrent connections
the number starts looking more reasonable.
At the moment I do not have a good rule of thumb for when I switch
from blob to something like MogileFS (which is what I have been moving
toward using).
