QT5.x performance with Neon enabled

[jasonuy]

Hi,

I'm new to QT so please bear with me. I built QT5.2 with Neon enabled. When I ran example apps like collidingmouse (in widget/graphicsview), I do not see any performance improvement over an image without Neon enabled. I had a look at some Neon optimized functions and I'm not sure if those are being used or not. My question is have people tried any Neon optimized code before and what is the expected improvement in performance? Is there a good example app that will really highlight the difference between Neon and non-Neon built images?

Thanks in advance.

Jason

Hi and welcome to devnet,

You should also add which system/OS/distribution/compiler you are using in order for others to comment the comparison.

Thanks for the tip. I'm building using ubuntu 12.04 (32 bit) and using gcc 4.6.3. (Ubuntu/Linary 4.6.3-1ubuntu6)
