I just ran a small tests against Apache Traffic Server, to see how performance has improved since last time. My test box is my desktop, an Intel Core i7-920 at 2.67Ghz (no overclocking), and the client runs on a separate box, over a cheap GigE network (two switches in between). Here are the latest results:
2,306,882 fetches on 450 conns, 450 max parallel, 2.306882E+08 bytes, in 15 seconds 100 mean bytes/fetch 153,792.0 fetches/sec, 1.537920E+07 bytes/sec msecs/connect: 5.326 mean, 13.078 max, 0.149 min msecs/first-response: 2.094 mean, 579.752 max, 0.099 min
This is of course for very small objects (100 bytes) served out of RAM cache, with HTTP keep-alive. Still respectable, close to 154k QPS out of a vey low end, commodity box.
