Sorry about that. I knew you said gigabit (that's Gb, btw, GB means
gigabyte) but I neglected a factor of 1024 in my calculations. You're
right, you're way under the bandwidth limit for a Gb Ethernet network.

Definitely something to look into. NIO uses some OS black magic that
might not be visible to your Java profiler. Perhaps use a native
profiler to see what's going on?

You might want to re-post with a more descriptive subject line...
something like "Observing significant latency using NIO Connector" or
something like that. You'll get the TC devs' attention with that one.
