Wim Bervoets commented on RF-1717:
----------------------------------
I've tried with the 3.1.x version. Here are my findings:
My testcase consists of 6 calendar components on one page. (and no other components)
- performance has definitely been improved on IE6. Where it took around 2sec per
inputfield (with attached calendar component) previously, it now takes around 1 à 1.5sec
for the 6 inputfields to render as a whole.
So it is still not instantaniously rendered but a lot better.. What's strange though
is, that if I press F5 to refresh the page, the speed reverts to the old pre-fix timings.
Not sure why.
I've been looking at the generated HTML and noticed that the Javascript is being
included after each inputfield (eg. once for each calendar):
At
http://developer.yahoo.com/performance/rules.html#js_bottom they recommend to put JS at
the bottom of the page if possible:
"With scripts, progressive rendering is blocked for all content below the script.
Moving scripts as low in the page as possible means there's more content above the
script that is rendered sooner."
I've tried this and the rendering of the inputboxes is then instantanuous. But my cpu
load still goes to 100% for a few seconds when the new Calendar()'s are being done
just before the </body> tag.
I hope this information is usefull for you.
Thanks already for the quick fixes!

Huge performance problem with the calendar component in IE 6
------------------------------------------------------------
Key: RF-1717
URL:
http://jira.jboss.com/jira/browse/RF-1717
Project: RichFaces
Issue Type: Bug
Affects Versions: 3.1.3
Environment: IE v6.0.2900.2180.xpxp_sp2_rtm.040803-2158
Firefox v2.0.0.11
JSF RI 1.2_07
Facelets 1.1.13
Seam 1.2.1
Richfaces 3.1.3
WebSphere v6.1.0.13
Reporter: Denis Forveille
Assigned To: Pavel Yaschenko
Priority: Critical
Fix For: 3.2.0, 3.1.4
We have a huge performance problem with the calendar component in v3.1.3 and IE (version
v6.0.2900.2180.xpxp_sp2_rtm.040803-2158)
It can take 10 to 30 seconds for IE to display a page that contains with a rich:calendar
component where the IE process is using 100% of the cpu
The problem does not occur with firefox v2.0.0.11
Also if we look at the memory usage of the IEXPLORE process, that grow constantly each
time we click on a page that use that component, it seems also that a memory leak is
occurring
