Hello,
I'm attacking the bottle necks in my app........ and I've just noticed
that XvShmPutImage is one of my bottlenecks. It takes 4 msecs to draw 1
512 x 256 sized frame.
What do you get for:
x11perf -repeat 1 -shmput500
If run in depth 24, the fps is roughly the bandwidth, in MB/sec
to the framebuffer.
I get
x11perf - X11 performance program, version 1.5
The XFree86 Project, Inc server version 40100001 on :0.0

Sync time adjustment is 0.0489 msecs.

Something is wrong with your system.
can I know on what figures and logic you draw this conclusion ? ... are
those figures too slow ?
What does "cat /proc/mtrr" say?
no such file or directory. I'm on debian.
And were there any warnings in the /var/log/XFree86.0.log (lines
that start "(WW)")?
(WW) Cannot open APM
...
(WW) Warning, couldn't open module xv
(II) UnloadModule: "xv"
(EE) Failed to load module "xv" (module does not exist, 0)

And this was a laptop right?
yep, dell inspiron 8200
Are you perhaps stuck in some
power saving mode?
dont think so, power saving has been turned off.........well, I have
disabled APM.
Mark.
