RF 4.3.4 is slow in IE8

[youth.9009]

Hi All,

I'm facing performance issue in IE8 and its works fine in other browser. I have a page which has three tabs and each tab has a extended data table.

When I click on the Tab, in IE9 it loads 400 ms but it takes 3 to 4 seconds in IE8.

When i enabled the ajax log, found that one extra action (Listing content of response changes element:) is happening in IE8 which takes 2 seconds.

I have given the ajax log below. So please help me in this issue as I cannot upgrade browser version due to some constraint on my environment.

IE8;

debug[15:24:38.365]: New request added to queue. Queue requestGroupingId changed to tabhdr2

debug[15:24:38.365]: Queue will wait 0ms before submit

Nice work with the AJAX log.

Can you debug and determine which of these two files is being hit:

https://github.com/richfaces/richfaces/blob/master/framework/src/main/resources/META-INF/resources/org.richfaces/ajax/log.js#L319

https://github.com/richfaces/richfaces/blob/master/framework/src/main/resources/META-INF/resources/org.richfaces/richfaces-jsf-log.js#L61

Can you also use the debugger to make sure those lines are being hit even when you aren't using the a4j:log component?

It is using org.richfaces/ajax/log.jss only and looks like we are not getting the extra log in IE9 as it is throwing some error.

These lines are not hit if I don’t use a4j:log.

Thanks.  Would you please file an issue w.r.t. IE 9 throwing the error when using a4j:log?
