I've been benchmarking trafficserver using ab. For a backend I'm using httpd with a module to insert a delay into each request, as a crude simulation of a heavyweight app likely to benefit from acceleration.
Results through trafficserver show most requests reported as failing with "length", meaning the contents aren't received in full (or at all). A short ab run with verbosity turned up shows lots of instances of: LOG: header received: HTTP/1.0 304 Not Modified^M Date: Mon, 21 Nov 2011 14:23:48 GMT^M Server: ATS/3.0.1^M ETag: "5e24-24cd-4b23b69f6e89c"^M Cache-Control: max-age=60^M Age: 2^M ^M WARNING: Response code not 2xx (304) According to ab, this is in response to: GET /testfile.html HTTP/1.0^M Host: localhost^M User-Agent: ApacheBench/2.3^M Accept: */*^M ^M i.e. an unconditional request! This looks infeasibly broken. Any clue what I'm missing? -- Nick Kew
