Tom, how's your NetV stuff going? Used it for anything interesting
yet?
I'm curious whether AOL has ever had their NV (NetV) became a
performance bottleneck. Even using TCP/IP, it is probably faster than
querying an RDBMS, although lots slower than using a local NSV in
shared memory. Since they are probably using it in a query-like
rather than nsv-in-an-inner-loop like fashion, my guess is it's
probably fast enough.
On the other hand, if you were really hitting NetV with lots
of small requests, the TCP/IP latency might bite you. In that case,
GAMMA
might be the answer. It supports very low latency reliable MPI over
cheap Intel PRO/1000 Gigabit Ethernet cards.
That seems like one of those atypical edge cases where "enterprise"
style server computing and high performance cluster computing overlap.
However, offhand I can't think of any web-oriented application at all
that is likely to be that latency sensitive. I'm curious whether
anyone has seen one.
