The performance of QtWebKit on Wince 6.0, including MIPS platform

[favor]

Hi, all

I just wonder what's the performance of QtWebKit on Wince 6.0, including MIPS platform?
I am confusing with this, I got this problem that webkit can't run normally as expected on MIPS.
the ram which can be used is 128M, but I got it low performance, and it load web page or local htm page faild, just show a blank white.
Please give us you opinions freely.

Does no one knows this?

hello,

what version of qt are you using??

I"m using qt 4.6.2 on imx51 Freescale board. The perfomances are acceptables, and I can load web page and local content. the only thing is that it has poor Javascript performances, I heard that it is maybe because there is no JIT enabled in qtwebkit for wince. I would like also improve Javascript performances if you find something, share with me.

Thanks,

I am using Qt 4.6.0 version on MIPS platform, and it can't load any web pages, even a static html page.
I don't know why is this?
and when I start the webbrowser demo, the serial console will prompt out errors like below:

Hi,all

I have a qtwebkit example compiled for MIPS on CE6, every time when I start the exmaple, it will prompt out error something like below; and the exmaple can't load any web pages at all, even local static html page.
The typical error is something like that:

Exception 'Alignment Error' (4): Thread-Id=05fe000a(pth=8791a6b8), Proc-Id=05fd000a(pprc=8654c6b8) 'simpleWeb.EXE', VM-active=05fd000a(pprc=8654c6b8) 'simpleWeb.EXE'
PC=41dc9094(qtwebkit4.dll+0x00389094) RA=41dc97bc(qtwebkit4.dll+0x003897bc) SP=0011d9c8, BVA=00000000

I found the reason of this exception, but I don't know if this data access abortion caused that webkit can't load any pages at all. is it the reason that caused webkit can't load anything at all? please give me a discussion, I would highly valued you views.

For the reason, please see:
