Eventmachine talk - Mar 2008 - Eventmachine utils

I''m working on StrokeDB* right now and put pieces of networking stuff
into a separate repository "Eventmachine utils". There are 3 useful
libs already: protocol chaining, messaging protocol and marshalled
messaging protocol. Check them out :-)

Overview:
http://gitorious.org/projects/eventmachine-utils

Files:

Chaining (em_chain.rb) seems to be extremely useful (at least, for me)
and seems to involve as little overhead, as possible. I''m going to do
some benchmarks soon.
SimpleMessageProtocol & MarshalProtocol are based on a chaining
facility.

I''ve done a simple benchmark-comparison for simplistic protocols
versus a fat stack of chained protocols. In a real-world applications
there might be 5-7% speed drop comparing to a simple message protocol
and 15-17% drop comparing with very naive approach of messaging with
EM''s receive_data & send_data (which is in general incorrect, but
fast
and suitable for data streaming or very custom protocols).
