Improving application performance

[Guest mrmartin]

Hi all

I ported a mobile album application to the qtek 8310 but I'm experiencing some performance issues. I have the same application on a Nokia N91 where it performs better.

The N91 has a smaller screen (176 x 208) so that woule be one major difference.

Since GAPI doesn't allow QVGA resolutions I have changed to PocketHAL. Does anyone have experience with this? Is it a known bottleneck?

I'm currently trying to eliminate the causes for the lack of performance and perhaps find out if there are any tweaks I could implement in the SP5 version.

What comes to mind first is that perhaps the file access isn't optimal. I'm using fopen which is not buffered. Does anyone know where I could find an API with buffered file reading for the SP5 platform?

One more thing could be that my application thread should have higher priority.

Any and all suggestions are greatly appreciated.

Thanks,

Martin

Hey what application are you talking about? And you have ported a symbian app to windows mobile?! Wow!

Can you give us a beta version to check out?

Hi

Sorry but this is a demo using our imaging platform and is not for public distribution. It will be available to phone manufacturers but to when and who I am bound by a NDA not to disclose.

Direct X or GAPI (should also work with QVGA, at least it does in TCPMP). Maybe you can ask the TCPMP guys how they do this.
