Jason, Do you have any of the longer textile reference documents online in textile source format. I wanted to try benchmarking redcloth on them and comparing it to what Maurico found benchmarking bluecloth. see: http://eigenclass.org/R2/writings/fast-extensible-... The markdown syntax document he is benchmarking is about 11k. You can see my results duplicating the bluecloth results here: http://gist.github.com/gists/91477 and in a graph: http://img.skitch.com/20090408-fp1sxu3fu7dm4296kqr... I was curious how fast redcloth would be at a comparable task and whether redcloth would also show non-linear processing times as the input document got larger.

No, they're all in individual entries in the CMS, but it shouldn't take me long to have it loop over them and dump as plain text... <r:find url="/textile/"> <r:children:each><r:children:each> <r:content part="input" /> <r:children:each> <r:content part="input" /> </r:children:each></r:children:each> </r:children:each> </r:find> Easy enough! The result is attached.

Thanks Jason, Here are some interesting results testing in MRI 1.8.6 and JRuby. Testing BlueCloth: http://img.skitch.com/20090411-fp1sxu3fu7dm4296kqr... Testing RedCloth: http://img.skitch.com/20090411-5is73f52ftck2h3pyiiyjiu2m.png

Interesting. Care to offer any interpretation?

BlueCloth is much slower and the time for processing increases quadratically as the input document get's larger. I haven't looked at why. RedCloth is about 15x faster and scales linearly -- again I'm not sure why but I like that behavior ;-) When most of the processing time is spent in Ruby regex's (bluecloth) JRuby is about twice as fast. Running RedCloth in JRuby however is only about 10% faster. From previous benchmarking of Hpricot I suspect that the ragel code in Java is just a bit slower than the C and the speedup is due to other areas where JRuby is faster. The context for the benchmarking is a blog post here: http://eigenclass.org/R2/writings/fast-extensible-... Mauricio's implementation of a simple markdown processor in OCaml appears to be about 20x faster than RedCloth. I'd like to know a good way of measuring "real" memory use when running a benchmark like this in Ruby especially one that involves a native library. Mauricio's reports very low memory usage from his OCaml implementation.

Awesome. Thanks, Stephen!
