Like reactivity access/security gateway, it processes incoming XML traffic,
sends HTTP or so requests to back end servers, to invoke web services. after
it gets the responses back, it will assemble XML responses then send back
to clients. I am guessing during this whole process, there must be something
that needs improve. How about a modified TCP/IP stack inside kernel?
e.g., a almost obsolete patch, T/TCP. any ideas?

pure software? then what's the benefit? you still need cpu cycles to process
tcp

i said for the gateway, e.g. reactivity's products.

normally it could be 5 times faster even just offload the tcp stuff to a NIC.
If tcp gets offloaded to an application gateway, it could be 10 times faster
depending on the application type. coz, not only the tcp itself gets speeded,
also the application protocols/payload get compressed, optimized, or whatever

usually the tcp checksum is offloaded to NICs, but not sure how much that
really benefits? XML accelerator can be useful

hehe, my question should be how to design a good offload engine, software.

I think what you need is really a TCP offload engine, right now, there are a
couple of NICs which can support this.
