So I've broken out the basic core code in the Cacheboy tree and re-used it in a simple TCP proxy.
I ripped off the SSL tunnelling code (thanks Duane, etc!) to implement the TCP proxy. It was -mostly- easy to do; there's always another strange thing lurking under the surface which I hadn't thought about. The changelog: http://code.google.com/p/cacheboy/source/list?path=/branches/CACHEBOY_PRE The tcp proxy as an example: http://code.google.com/p/cacheboy/source/browse/branches/CACHEBOY_PRE/app/tcptest Basic profiling results (over a LAN; I haven't yet setup a proper WAN emulation environment; thats next weeks' task!): http://cacheboy.blogspot.com/2008/06/heres-output-trace-im-running-it-on-sun.html The user-space CPU usage is about 5% at the moment, but 10% of that is vfprintf() and sub-calls. In a -tcp proxy-. Gah! adrian
