Hi All,
I have tried clutter 1.0 ELGX with both Angstrom and Ubuntu and while
running my application, Ubuntu is giving better performance than
Angstrom.Why it's like that ?
The performance issue is noticed with click event response time and
animations(movement of actors).And in ubuntu same applications are
giving normal performance as in Desktop PC's.
I have tried the different parameters which is normally effecting the
performance like Resolution(My application is running on 640x480),
Tried to redefined Video Ram.But still the performance difference is
there.
So is any other parameter is need to be enable for getting better
performance with Angstrom.
Are you using the same SGX SDK on both platforms? If not, please report the version of the slow one.
regards,
Koen
Siji, your question has too many unknowns... What versions are you
running of both systems? System setup? swap partitions/different sd
cards/etc can all swing it...
Note the kernel might be misleading you... In my testing, with any
kernel > 2.6.30ish the mouse movements are very responsive no matter
the load on the cpu.. At times 2.6.29 seemed to bog down the
usb/mouse (personal observation).. This could lead to the appearance
of a faster system..
Otherwise, Angstrom should be faster then karmic (9.10).. And lucid
should be about even, if not slightly slower...
Some of my own results are here:

Currently retesting those results, as i didn't originally test
angstrom...

Yes, Am using the same SGX SDK which has been provided my TI (
OMAP35x_Graphics_SDK_3_00_00_09).As you mentioned somewhere in
tutorial, still clutter* 1.0 having any issue on OMAP.
So is any other parameter is need to be enable for getting better
performance with Angstrom.

Hi Robert,
Am using C3 beagle board with 2GB SD card, having two partitions one
is 700MB for uImage and remaining for Rootfs.
And In angstrom SD card, I build X11-image by using OE with kernel
2.6.29.In ubuntu also am using the same kernel version.
What you meant by swap partition, is it essential for Embedded OS?

OK, I will give a try with 2.6.30 kernel.
If they are both 2.6.29, then i have no idea why... 
A swap partition is useful when you start running out of main system
ram... (multiple gui applications open...)

Can you pls describe about how to cerate swap partition.Is the
procedure is same as for the desktop OS.
