Your slides are extremely cool! I have a few off-topic questions:
1. Where did you get these nice photos? very cool!
2. What tool did you use to draw diagrams and to export the slides to PDF?
I love your style! :)
And of course, its content was superb, too! I bet the audiences were
fascinated by your presentation. :D How hot was the fever? What questions
did you get?
For other people, here's Peter's blog post regarding the ApacheCon session

Be sure to read http://en.wikipedia.org/wiki/Nagle's_algorithm :)
I think your usage is absolutely fine. Another way to achieve the
same may be to drop down the MSS, but I'm not sure if we can do that
from within java (maybe some of the outbound buffers help control that)

Very cool indeed.
Thanks for posting these peter and for giving red5 a plug :)
One thing i noticed...
"For ultra-low latency with small message sizes on a local
lan, disable Nagle's algorithm; the TCP_NODELAY flag. "
We do that now on for all sessions. Is it a bad thing to be using it
for connections over internet not local lan? The packets we send are
usually quite small under 1-2k, and latency is really really important
to us. I think we have seen an improvement since using it, just want
to check it if it has any side effects.
Will show these slides to anyone new to mina.

Diagrams were done with <http://www.omnigroup.com/applications/
omnigraffle/> , and the presentation was done with Keynote <http://

A few about threads and memory usage, difference between heap/direct
buffers, then some performance related questions too. The room was
mostly-full, which was nice. Hopefully some more people will poke
their head in here because of it :)
