That MTRR issue is probably tied up with your graphics card - as I suspect Wampas suggestion will say.
So it's probably good to get it fixed, but it's not going to affect your network speed. |

Well, i am geting this :
| Code: | bash-2.05b$ cat /proc/mtrr
reg00: base=0x00000000 ( 0MB), size= 512MB: write-back, count=1
reg01: base=0xd0000000 (3328MB), size= 16MB: write-combining, count=1
reg02: base=0xe0000000 (3584MB), size= 256MB: write-combining, count=1 |
For Radeon 9700 128MB 
And dmesg says :
| Code: | # dmesg | grep fglrx
fglrx: module license 'Proprietary. (C) 2002 - ATI Technologies, Starnberg, GERMANY' taints kernel.
[fglrx] Maximum main memory to use for locked dma buffers: 430 MBytes.

I use VESA for console, it allocates the 16MB that explains the /proc/mtrr status : in dmesg i have :
| Code: | Linux agpgart interface v0.100 (c) Dave Jones

Tried to see what could be done using a /sbin/mtrr.sh file as follows as suggested in the link i posted above :
| Code: | #echo "disable1" >| /proc/mtrr
#echo "base=0xd0000000 size=0x8000000 type=write-combining" >| /proc/mtrr
|
But unfortunately it does not work
Maybe i did something wrong in mtrr.sh .. ><
I am using gentoo-dev-sources 2.6.9-r4 and latest ati drivers, dri/opengl enabled but no MTRR and it seems to be slowing down 3D acceleretation.
Seen a few posts about it on the web, but no solution appart the link i posted above, that unfortunately i can't get to work, didnt find the right parameters for me. It seemed to occur mainly on 2.6 kernels.

Try "disable=1" rather than "disable1". And both lines are commented...

You mean it's not enabled in the kernel config? |

They were not commented of course in my mtrr.sh file.
| Code: | | You mean it's not enabled in the kernel config? |
I had it compiled 1st in the kernel, and with mtrr "on" or "off" in xorg.conf i was geting same results.
Then i completely removed MTRR in the kernel, and it changed nothing. And still FPS on glxgears cap'd at 1550.
I re-compiled lately my kernel with MTRR support, and used ati-drivers 3.2.8 and it works i get 2250 fps or so.. Sometihng is wrong  .. Sidenote, i then get ~150FPS on fgl_glxgears with 3.2.8 drivers when i was geting 300+ with 3.14.6. Maybe not the right forums to talk about these drivers though sowwy. 
Btw in /proc/mtrr it seems one of the lines is aperture size, so since i have 256MB aperture in bios it looks like this :
| Code: | reg00: base=0x00000000 ( 0MB), size= 512MB: write-back, count=1
reg01: base=0xd0000000 (3328MB), size= 128MB: write-combining, count=13
reg02: base=0xe0000000 (3584MB), size= 256MB: write-combining, count=1 |
