Thanks Mrinal for sharing this. The tweak was very helpful for me to reduce the time to compile my code.

Amar,

Xmx specifies the max value of memory that FlexBuilder is aloud to use, provided you have that much physical memory .. how much RAM do you have on your system? … if its less than the Xmx value then FlexBuilder would fail to initialize.

on my pc when i do liek this it Failed to initialize(start) Flex Builder ..it only takes Xmxupto 512m …not more than this value
Don’t know if it really works on other PCs or not but on mine it really does’nt work dude.

Well you can make that statement, the standalone flex builder is a basic eclipse with the flex plugin installed. You can take the standalone version and add any other eclipse plugins, effectively turning it into a normal eclipse installation.

Flex Builder is essentially Eclipse this statement is not technically right , Flex Builder comes in two variants as an Eclipse Plugin and Rcp .You cannot call it as an eclipse

Thanks and Regards

Dan,

Your comment above made sense so I replaced both the SWCs (degrafa and pv3d) with external source paths, but still not much improvement .. the project takes over a minute to compile.

My earlier suspicion was embedded assets like fonts etc .. but getting rid of all of them did not help either.

I know that if you are using really large ( or many ) SWCs you need to bump up this number because when the compiler links your source to the SWC, I assume it loads the entire thing into memory to do it.

In terms of speed I would also have to assume linking to the source is faster, it doesn’t have to navigate the SWC to find where to link to, just resolve it to another file.

Hi Dan,

The project uses 2 SWCs .. I have used the same 2 SWCs in other projects too and they work fine, so I don’t think they are the cause of the slowdown .. although now that you mentioned it I wonder what compiles faster .. an included swc or an external source path?

Are you using a lot of SWCs in this project?
