Memory keeps increasing even if system left idle

With the docs in Ext 2.2, i see the memory hovering at 41.316 mb +/- 250K

a sample of 10 minutes, with the loaded documentation API i see relatively little change. I do see internet explorer about:blank increasing memory every now and then, but it's not HUGE chunks.

ya i also notice such differenc in ext 2.2 examples in IE,which was not observed in 2.0 that their were some instance where memory for panel is released especially tabpanel example , i think memory leak maybe addressed in extjs 2.2

i am also not sure about memory growing issue with ie which i came across with my application.and also cannot able to test in 2.2 examples.

probably need to test this with my application and then only i can revert on this.

we are using gwt-ext 2.0.4 and extjs 2.0 and performance become bottleneck in IE for us , maybe upgrade to 2.2 will resolve this , but need to see whether gwt-ext support extjs 2.2
if you have any idea about this please revert me back.


Thanks for all your help , really appreciated.

Finally i had upgrade to extjs 2.2 and then also same problem persist , still their is performance hits in IE.

I had also applied the patch as mention in one of extjs forum , but no use

The memory allocated by windows component is not garbage collected their is not even 1mb decrease in memory allocated , at some instance i had observed memory release in case of panels but not much.

conclusion : if their is no proper solution and patch for this bugs
I think its of no use for developing enterprise wide desktop like application using this framework. it can be better to use as javascript library as any other in which page refresh at every instance.

if someone can help fro ext team, i can host this application online to test.

Hi

I can replicate this issue with touch 2.0 running on latest chrome browser. There is an occasional javascript garbage collection (but this changes from browser to browser). What is the exact reason for this behavior?

Thanks.
