Adobe Flashbuilder 4.7 Performance is Slow

Hi,

My team was using Adobe Flash Builder 4.5 and performance was Good. But recently we migrated to Flashbuilder 4.7.

The performance is very slow. For each and every code modification (Auto build enebled), it is taking more than 15 mins to get back to work (Even in a high confirguration 8GB machine). Sometimes even FlashBuilder closes telling "Insufficient Heap Memory"

We have tried increasing the memory size in FlashBuilder.ini file. But still there is no improvement.

Can you please advice me on some improvements ?

Thank you in advance.

Arun.
