Strange response time pattern + Cocoon performance
I have noticed something very strange in cocoon log :
/CocoonServlet: 'cdn/dataold/goods' Processed by Apache Cocoon 2.1-dev in 291 milliseconds.
/CocoonServlet: 'cdn/dataold/goods' Processed by Apache Cocoon 2.1-dev in 511 milliseconds.
/CocoonServlet: 'cdn/dataold/goods' Processed by Apache Cocoon 2.1-dev in 290 milliseconds.
/CocoonServlet: 'cdn/dataold/goods' Processed by Apache Cocoon 2.1-dev in 541 milliseconds.
/CocoonServlet: 'cdn/dataold/goods' Processed by Apache Cocoon 2.1-dev in 290 milliseconds.
/CocoonServlet: 'cdn/dataold/goods' Processed by Apache Cocoon 2.1-dev in 511 milliseconds.
/CocoonServlet: 'cdn/dataold/goods' Processed by Apache Cocoon 2.1-dev in 291 milliseconds.
/CocoonServlet: 'cdn/dataold/goods' Processed by Apache Cocoon 2.1-dev in 511 milliseconds.
/CocoonServlet: 'cdn/dataold/goods' Processed by Apache Cocoon 2.1-dev in 290 milliseconds.
/CocoonServlet: 'cdn/dataold/goods' Processed by Apache Cocoon 2.1-dev in 510 milliseconds.
/CocoonServlet: 'cdn/dataold/goods' Processed by Apache Cocoon 2.1-dev in 280 milliseconds.
/CocoonServlet: 'cdn/dataold/goods' Processed by Apache Cocoon 2.1-dev in 531 milliseconds.
/CocoonServlet: 'cdn/dataold/goods' Processed by Apache Cocoon 2.1-dev in 310 milliseconds.
/CocoonServlet: 'cdn/dataold/goods' Processed by Apache Cocoon 2.1-dev in 521 milliseconds.
These are subsequent calls to url from IE. The xsp is very simple:
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsp:page language="java" xmlns:xsp="http://apache.org/xsp" xmlns:esql="http://apache.org/cocoon/SQL/v2">
<content>
<esql:connection>
<esql:pool>cdn</esql:pool>
<esql:execute-query>
<esql:query>select Twr_TwrId, Twr_Grupa, Twr_EAN from cdn.towary</esql:query>
<esql:results>
<esql:row-results>
<row>
<esql:get-columns/>
</row>
</esql:row-results>
</esql:results>
</esql:execute-query>
</esql:connection>
</content>
</xsp:page>
I have been reporting also some performance problems concering xsp + esql (dev
snapshot from April vs snaspshot from July gave nearly 2 times lower response
times).
>From that time I have switched to Windows XP (everyting remained the same -
database, jdbc driver, tomcat version).
Yesterday I've downloaded new cocoon dev snapshot and I am shocked. What
*ALWAYS* took less than 400-500 ms now took more than 2 seconds !! I'm still
praying that it's Windows XP
I'm going to recheck the problem on some older cocoon version later this day
ouzo

Ah, my goof. Had my mind in 2.0.3. Sorry.

He was using 2.1, and complaining that it is much slower. I meant 2.0.4,
which might be faster.

2.1 has lots of changes, including redesigned pipelines with much longer
keys, which can be cause for some slowdown.

Why? What is the fix you're thinking affects him?
