I only have one large instance live. My impression from previously is that
between host bandwidth is generally about what you saw. We have been able
to sustain 20-30MB/s into EC2 to a single node which should be harder than
moving data between nodes. I have heard rumors that others were able to
Ok, good. Based on the comparison of perf numbers, and Ted's experience
with large instances on ec2 running zk, this makes sense to me. A large
is about half (very roughly) the horsepower of what I was using for my
tests. Ted mentioned that he hasn't seen issues on ec2 running with

The server side is a fairly standard (but old) config:

Most of our clients now use 5 seconds as the timeout, but I think that we
went to longer timeouts in the past. Without digging in to determine the

Can you elaborate on gc tuning - you are using the incremental collector?

Several of our search engines use pretty large heaps (12-24GB). That means
that if they *ever* do a full collection, disaster ensues because it can
take so long.
That means that we have to use concurrent collectors as much as possible and
make sure that the concurrent collectors get all the
Worked pretty well for me. We did extend all of our timeouts. The biggest
worry for us was timeouts on the client side. The ZK server side was no
problem in that respect.
