Is GWT preferable for large scale projects similar to FB?

[mvj]

Hi all...

I'm a newbie to GWT. I mean just started learning it. So I want to ask
that for a large scale project (web app ike Facebook) is GWT
preferable? Why? We are confused whether to go for pure JSP/servlets
or GWT like framework? Thanking in advance....

Yep, it certainly is. 

Don't forget it was used to build Google Wave.

And pretty soon his current code splitting will be further optimized which is great for bigger app's (like mine which).

The "mission" statement of GWT: Building high performance interactive websites.

BTW: I don't see Facebook as a "big" front-end..

If speed is critical for your application then there are 2 things to consider:

1. Speed after the application is loaded.
2. Speed in which the application loads up. 

If you are concerned about latter, then you have to either use code splitting or consider moving to jsp. Because in a large application the code size could easily cross 1.5 MB which might take a long time to load. 

If the former is of importance(which actually makes the app interactive) then GWT is definitely the way to go.

> easily cross 1.5 MB

I don't agree with "easily".

A few things:

- Perform efficient coding.

- Use Soyc to optimize your code splitting.

- Transferring the files gzipped between browser and server will deliver a file reduction of about 50%..

- Using multiple modules if size is getting too big.

- etc..

Result: It's hard too cross an 1.0 MB initial load.
