Subject Re: eBay Case Study and Synapse

Wearing my old Synapse Hat on again.., thats certainly good to hear!

When I first started working on a non-blocking HTTP transport [1] and 
wrote the implementation based on HttpComponents [2] almost 4-5 years 
ago, I didn't imagine that it would someday drive traffic at eBay! 
Credit for this also goes to the Apache HttpCore/NIO project, and 
especially to Oleg Kalnichevski who helped us immensely to get NHTTP 
going in those early days


Getting back to the present from 4-5 years back .. The UltraESB shows 
that much better performance levels can be easily achieved today with a 
further improved NIO implementation utilizing Zero-Copy proxying [3] and 
well designed and clean code. Now that means any further X times 
improvement in performance would yield X times savings for a user. It 
would be interesting to do a performance comparison..
