There is no test. But this is my observation with so many roms of Froyo and Gingerbread.
After comparing both the OS, I found froyo to be more stable on Defy and hence worked out this rom.
I tested this on quadrant score of 1393 and the GPS fix is done in 9 seconds
the camera gets the location in 3 seconds... Also camera is more responsive in this rom.
After Installing, install your favourite browser and favourite file browser as I have removed the stock browser and file manager as Market has much better options.
If I keep them, they will unnecessarily be seen in the menu and eat RAM/Battery and many guys dont use them. Hence decided to remove them.
