Speed of 3.1 apps slower than 2.2?

[Bucs]

I am definitely seeing a very noticeable difference in load times of pre-configured components under 3.1 as they are loaded for the first time into my application panel area. 2.2 seems MUCH crisper when using the exact same code base to switch between these components.

Anybody else seeing this? Is there a trick to speedng up 3.1 component load times? Are there new "no-no" or any gotchas that we now have to avoid in 3.1 that will impact performance?

Thanks

test case code would helpful for forming opinions and answers

The performance of Component rendering and layout is being looked at as a priority right now.

The 3.1.1 release will specifically address this issue.

Thank you Animal. I was getting worried.

@http,
I didn't see the point in posting any code as it's the exact same code in both instances and it's very fast under 2.2 and a definitely slower in 3.1.

Thanks...

The work done by @Meroy has been amazing. I've seen first hand how many improvements can be made. I'm glad the team (and senior community members, such as @Animal) are looking at it.

Although I'm sure this question has already been asked plenty of times, is there any idea on exactly when the 3.1.1 release may happen?

Was in the middle of upgrading an app to 3.1.0 when I discovered the MIF extension issue where it's not going to be updated until a stable release of 3.1.1 comes out. So I'm kinda stuck in limbo land as the app makes extensive (no pun intended) use of the MIF. It would just be nice to have a ball-park guestimate of projected release date.

Thanks

That's what happens when you depend on a 3rd part plugin/extension. :-\

[Bucs]

True, but that is also why the framework is so valuable, so that you can use off the shelf functionality that does incredible things without having to write it all yourself from scratch. The ability to extend the framework with community controls is a major selling point of ExtJS. So if you aren't using ANY of the extensions to accomplish certain UI tasks, and are programming them all yourself, then you're the man. I've watched your vids, so I know you CAN do it all yourself, but from an profitability perspective, why would you want to? Getting temporarily handcuffed by extensions during the upgrade path of ExtJS is a necessary evil, but is still worth the trade off imo.

I wasn't b!tch!ing about the control dependence or even the release date, just trying to get an idea on timing. I can resume coding on the 2.2 app and port those files over when 3.1.1 is available, so not REALLY in limbo land like I claimed

I would like to say thanks - but hell no, I can't do it all by myself. Wish i could though.

It appears that progress is being made in the current trunk. However, resizing is now bad with it -- try resizing the examples/portal/portal.html demo.

It goes back and forth. Resizing was fine with build 5931, but rendering was bad with it. Now, rendering is back with 5933+, but resizing may suffer for some apps with this one.

There are pairs below. The first of which are 10 tabs followed by another 10 tabs. This was done for all four (Basic Forms, Forms with HTML Editor, Grids and Form/Table combination). The latter is very expensive to render.

The surprise here for me was in seeing the BLD D3 results under IE 8. The same goes with the Safari/Chrome/AIR results. Firefox also benefits too, but not as much.
