Hi All,

   I am drawing two bitmaps alternatively on a click on Left soft key. I
found one thing that, Drawing bitmap is very slow, also the event handling
is very slow.

   Like say suppose I am calling InvalidateRect on pressing of left soft
key, So in return it will call WM_PAINT, there I am bitbliting by bitmap.
Now if I repeatedly press left soft key say for 10 times than the paint
event is getting called only 5 or 6 times.
   Is drawing bitmap is slow in Windows Mobile than Symbian Mobiles?
   Is event handling is slow on Windows Mobile than Symbian Mobiles?

Are you using an emulator, or real phones when you're trying those things?

You need to compare real phones, and then look at the speed of the processors on those phones, how much memory they have, etc. etc.

Generally speaking, you'll quickly discover that Windows Mobile is *FAR* slower compared to Symbian.

I don't know about the real device, but ya, the emulator is really slow one. The event handling is very slow, we have to wait till the first event get finish, unless it will just negelect that event.

Currently i am testing my application on emulator. As i found that there is some speed issue with the Windows Smartphone Emulator.

What about the phones themselves?  I have a Windows Mobile app that I would like to port to Symbian phones.  It is CPU bound by extensive signal analysis code that has nothing to do with the operating system.  Most Windows Mobile devices are 200 MHz to 500 MHz ARM processors.  What about the phones that run Symbian?

I got the impression that on average the clock speeds of the ARM processors in Symbian phones are a little lower than for the Windows machines, but for various reasons the CPU speed advantage (sometimes double the speed) often does not translate into a comparable overall speed-up.

Even tasks that just calculate things without any I/O might be influenced by the speed of the memory interface as strongly as by the CPU speed itself.

I read more than once that some versions of Nokia's Communicators are a little sluggish, with CPU speeds of only 150 MHz, but other models seem to be ok in general.

Actually this may be good news to me.  One of the problems with Windows Mobile with my application (professional piano tuning) is that you only get about 5 hours of running time out of the battery.  If a slower CPU speed can translate into longer battery life, and if I can get my application to work under the slower speed, then maybe a piano tuner can use the program all day long on a single charge.  That would be good.
