Hi strk,
During these days, I try to use the same
way(http://www.amdmi3.ru/gnash/) to test Gnash 0.8.5 performance on x86
desktop. You can look the result as below.
* gnash+cairo configuration:
./configure --enable-gui=gtk --enable-renderer=cairo --enable-media=gst
--enable-cairo --enable-gstreamer --enable-plugins --enable-npapi
--with-gstreamer-incl=/usr/include/gstreamer-0.10/
--with-gstreamer-lib=/usr/lib
* gnash+agg configuration:
./configure --enable-gui=gtk --enable-renderer=agg --enable-media=gst
--enable-agg --enable-gstreamer --enable-plugins --enable-npapi
--with-gstreamer-incl=/usr/include/gstreamer-0.10/
--with-gstreamer-lib=/usr/lib
* testing computer: Intel(R) Core(TM)2 CPU 6320 @ 1.86GHz
* below table is detail information of my testing swf file.

ps: delay = real time - movie length
I just want to use software to do the render, I don't have the hardware
acceleration.
In gnash homepage, we can see Gnash could support most SWFv7. So, in
this time, I only test SWFv4 and SWFv5, these file version is lower than
SWFv7. But, after check the result, the latest gnash still exist some
delay for playing SWFv5.
Do you have any idea to improve them? I want to try to improve it.
I don't know what difference between different swf version(SWFv4, SWFv5,
SWFv6, ....SWFv8). But in my test, I found when gnash play the higher
swf version file it has much delay time. If I want to know more details,
where to get the
spec.?http://www.adobe.com/devnet/swf/pdf/swf_file_format_spec_v10.pdf
(Is this spec?) Do I need to study the spec.?
Before I also ask you about skia render issue. You give a page
(http://www.gnashdev.org/?q=node/57). After reading this page, I also
don't know skia performance compare with Cairo and Agg. Does bjacques
try to integrate skia to the gnash? If not, can you help to estimate the
effort? (2 months/ per person)
I wonder try to improve gnash performance, but I don't have any idea to
do this work now. If I want to do it by myself(only one), what something
and effort can I do?
Best regards,
strk ??:

Hi strk,
Can I ask you a question?
Do you know any benchmark tool to test swf player performance? I found a
page, http://www.amdmi3.ru/gnash/, it only used script to test the time.
I can do it by myself.
I want to compare adobe flash, gnash and swfdec performance, I want to
get more accurate number. I don't know what factor affect swf player
performance, only render?
Have you been to compare them before?
Using AS to profile lets you compare all players.
For free-software specific profiling you may use oprofile or gprof.
Rendering i usually the bottleneck, but could also be something else...
