[CLOSED] Works fine on other browsers (like chrome) but Rendering in IE is slow

Hi,

Rendering of ext control on IE is very slow. We have consulted with microsoft team to regarding the same and their response is stated below.

Out of 5 dumps 4 of them shows jscript running which is part of ?Ext JS 4.2? from https://www.sencha.com/store/extjs . Example

23 jscript9!Js::JavascriptFunction::CallFunction+0xc4
                FunctionBody: 144e9d08
                Type: jscript9!Js::JavascriptFunction
                Name: beforeSetPosition
                Size: 115
function(){var b=this,c=b.callParent(arguments),a;if(c){a=b.adjustPosition(c.x,c.y);c.x=a.x;c.y=a.y}return c||null}
 
24 jscript9!Js::JavascriptFunction::EntryApply+0x39b
25 Undefined
26 jscript9!Js::JavascriptFunction::CallFunction+0xc4
                FunctionBody: 18781888
                Type: jscript9!Js::JavascriptFunction
                Name: setPosition
                Size: 345
function(a,e,b){var c=this,d=c.beforeSetPosition.apply(c,arguments);if(d&&c.rendered){a=d.x;e=d.y;if(b){if(a!==c.getLocalX()||e!==c.getLocalY()){c.stopAnimation();c.animate(Ext.apply({duration:1000,listeners:{afteranimate:Ext.Function.bind(c.afterSetPosition,c,[a,e])},to:{x:a,y:e}},b))}}else{c.setLocalXY(a,e);c.afterSetPosition(a,e)}}return c}
 
27 jscript9!Js::InterpreterStackFrame::OP_CallI+0x43
28 jscript9!Js::InterpreterStackFrame::Process+0x78f
29 jscript9!Js::InterpreterStackFrame::ProcessThunk+0x65

                FunctionBody: 144ec0d8
                Type: jscript9!Js::JavascriptFunction
                Name: setPagePosition
                Size: 400
function(a,g,b){var c=this,d,e;if(Ext.isArray(a)){g=a[1];a=a[0]}c.pageX=a;c.pageY=g;if(c.floating){if(c.isContainedFloater()){e=c.floatParent.getTargetEl().getViewRegion();if(Ext.isNumber(a)&&Ext.isNumber(e.left)){a-=e.left}if(Ext.isNumber(g)&&Ext.isNumber(e.top)){g-=e.top}}else{d=c.el.translateXY(a,g);a=d.x;g=d.y}c.setPosition(a,g,b)}else{d=c.el.translateXY(a,g);c.setPosition(d.x,d.y,b)}return c}

Can anybody give me some idea/hints so that I can resolve this issue.

Hi @asolvent,

I don't quite understand what the answer of Microsoft people states. Do you understand?

What do they suggest to improve the situation?

Did they explain why it works well in Chrome?:)

Our recommendation is to read this thread.
