Hi
I heighten everybody's mood I'll post some positive news.
After some optimizations in both Seaside and AJP I managed to break 8000
requests / sec with a single Pharo 1.3 image. Thanks to SystemProfiler I
knew where to look.
This is with a single request handler that just returns a two byte
response. It doesn't involve any rendering, sessions, continuations or
whatsoever but it kicks on the full Seaside request handling machinery
with a request context and everything.
I'm using WASmallRequestHandler from the Seaside-Benchmark package.
WASmallRequestHandler >> #handleFiltered: aRequestContext
aRequestContext respond: [ :response |
response
binary;
contentType: WAMimeType textHtml;
nextPutAll: 'OK' asByteArray ]
Apache 2.2.21 mpm_worker mod_proxy_ajp
CPU Intel(R) Core(TM)2 Duo CPU E7500 @ 2.93GHz
SmalltalkImage current vmVersion 'Croquet Closure Cog VM [CoInterpreter
VMMaker.oscog-eem.138]'
Attached you'll find the output of ApacheBench.
Cheers
Philippe
