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? | z**r

发帖数: 17771 | 4 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 | m**t

really benefits? XML accelerator can be useful

发帖数: 2454 | 6 hehe, my question should be how to design a good offload engine, software.

发帖数: 17771 | 7 I think what you need is really a TCP offload engine, right now, there are a
couple of NICs which can support this.
