@Sencha

I wonder if Sencha could leverage more knowledge and skills from the EXTJS community to help improve EXTJS’s performance.

The basic idea being…. Sencha identifies a set of heavily...

Remove array push in favour of array index.

index's are much quicker on none V8 browsers.

@Don, Good work, I can see a lot of fixes in this release. Can you confirm what's happening with the framework performance issues? Specifically in IE 7/8 but effecting the all browsers in general...

4.1.2 GA, The release notes don't refer to any Performance gains. Can you confirm what the status of this issue is?

4.1.2 was supposed to be a performance release, it just looks like a stack of...

That's very interesting. Could the EXTJS Dev team confirm if setting the width to 0 (when items are set to hidden) is a standard approach for other components in the framework?

No problem at all. Here are the revised timings with the start timer moved below the framework js file.


I'm running nightly build 4.1.2.268


Ext4.1.2 (after) > 5.131 Seconds

Thanks for taking the time to refactor the test case. There's a lot of re working in there!!!

Timings wise, I get an improvement. As follows (using 4.1.2)

You've listed server and client side code. Are you just talking about 1 or both?

In its simplest 101 form....

Right click, save page as, edit page / recraft the source path's and adjust the code to suite your malicious needs, save changes, run page.

[by MrSparks]

That’s an Interesting way of looking at it but it's placing the trust on the user, which of course you can never do. Fundamentally if the sever side controls have been developed correctly, there is...

You're welcome :)

Its an overall framework performance increase we are looking for rather than a specific area. It's still a away of the goal of equalling or bettering 3.x (especially under IE). All the previous test...

@EXTJS Dev,

Do you have any updates on how 4.2 is looking and if you have made up and ground in terms of performance? I think that was the focus of your efforts for this release?

@joeri,
Incorrect, you should always have Server Side protection/validation/encoding/decoding etc to ensure that the data that’s being sent or received by the client is as you require/is to the...

[by MrSparks]

My 2 cents. The lack of Client side XSS protection shouldn't be an issue because you should "always" protect server side. Anything that Sencha build into the framework can be very easily hacked out...

@sword-it

Thanks for that. Very helpful indeed :)

Is it possible to style the button with a gradient? i.e. like the example provided by Chandan.behura

[by MrSparks]

Only Sencha can answer that. If you don't get an answer on the forum, maybe email support or sales and see what they say.
Good luck.

[by MrSparks]

The API docs say its support but it doesn't seem to work for me. Sencha Dev will be able to confirm if its a bug in 4.1.1 or if its just not fully functional yet.

[by MrSparks]

@skirtle,

Sure but first I think there is a bug in the framework (in 4.1.2 anyway ). If you take a look at the following Sencha examples will see that in 1 and 2 the config is set as loadmask:...
