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

> 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
