Wim Bervoets commented on RF-1717:
----------------------------------
Some more findings:
Moving the scripts down just before the </body> tag really helps. I think this
concept could also speed up other richfaces components using inline javascript if applied
to them.
There is still something strange happening though when pressing F5 (on some PCs and not
others ;-)):
my PC: iexplorer process takes 7-9secs at 100% CPU time (this is IE6 SP1 on Win2000)
collegue laptop PC: iexplorer process takes 1sec at 100% CPU time (this is IE6 SP1 on
Win2000)
collegue other PC: iexplorer process takes 7-9secs at 100% CPU time (this is IE6 on
Win2000)
So same OS, same IE version, different hardware results in different speed results.
I'll need todo some investigation why.
I hope you can investigate if it's possible to move the rendering of the scripts down
in the HTML - with this the performance is good on IE6.
Kind regards,
Wim
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
