TreeProcessor speed
Hi team,
I just did some time measurements to compare the compiled and
interpreted sitemap engines. The tests were done on a 1GHz Win2K PC
running JDK 1.3.1/server hotspot and Tomcat 4.0.
I used "ab" to load-test two pages with 1000 requests :
- the welcome page (cocoon/welcome) which involves a simple
generate/transform/serialize pipeline
- the main docs page (cocoon/documents/index.html) which is a huge
aggregation of "cocoon:" sources.
Several 1000 page requests were run and their result ignored to allow
the hotspot to do its job.
The results are as follows, in requets/second :
page | compiled |interpreted |
---------+------------+------------|
welcome | 105 | 115 |
docs | 37 | 35 |
These results are quite encouraging since simple pipelines are a faster
in interpreted mode.
For the "docs" page, I have to check the code for both aggregate and
cocoon: to gain the few millisecs that are needed to beat the compiled
engine ;

All I can say is 'great job' and keep it up!
