I have done this before (http://www.zope.org/Members/BwanaZulia/benchmarks.html) but I just got my hands on a brand new server and thought I would see how 2.2.1 does. Machine: 600 MHz, 128 MB Ram, 20 GB EIDE drive, Linux 6.2 Ran it 5 times.. always came out close to this (+/- 1 RPS) Server Software: Zope/Zope Server Port: 80 Document Path: /index_html Document Length: 184 bytes Concurrency Level: 25 Time taken for tests: 9.715 seconds Complete requests: 1000 Failed requests: 0 Total transferred: 387387 bytes HTML transferred: 184184 bytes Requests per second: 102.93 Transfer rate: 39.88 kb/s received Connnection Times (ms) min avg max Connect: 0 5 254 Processing: 100 234 36 Total: 100 239 290 And Apache which I ran a lot. The RPS were anywhere from 250-850.. so this was about average of all of them. Server Software: Apache/1.3.12 Server Port: 8080 Document Path: /index.html Document Length: 231 bytes Concurrency Level: 25 Time taken for tests: 1.896 seconds Complete requests: 1000 Failed requests: 0 Total transferred: 520520 bytes HTML transferred: 231231 bytes Requests per second: 527.43 Transfer rate: 274.54 kb/s received Connnection Times (ms) min avg max Connect: 0 3 27 Processing: 18 42 706 Total: 18 45 733 Interesting as I upped the anti (requests and concurrency) Zope stuck to about 95-100 RPS and Apache started to lower (250-650). Disclaimer: This was a totally static test and it only shows how fast Zope can serve up static pages as Apache certainly does not have all the features of Zope. This is not very scientific just interesting. Take a look the page linked at the top if you want to have look at some other tests. J
