Better hardware - worse performance


Hello,

My system is (and was) Slackware 13 64bit

I had DFI LanParty NF4 with AMD Athlon64, 2GB (dual channel) of RAM and Gigabyte GeForce 250 1GB.

Now I have Asus P6X58D Premium with Intel i7 960, 6GB (triple) of RAM and the same graphics card

+ 3 internal SATA hard disks (no partitions change).
==========

I replaced hardware and noticed a performance drop.

In text console it looks like slow screen refresh. Also visible during boot when next line of text appears with a delay.
I can even see as midnight commander blue window unfolds from the top of the screen when I start it. Switching from text to X takes more time. File copying takes more time.

I have Xp guest in VmWare Workstation. Windows runs noticeably faster.

I have reinstalled Slackware and changed (in BIOS) default IDE mode for SATA to AHCI. Still slower then with previous hardware.

Maybe I am too oversensitive now, but I think moving around in BIOS is not smooth either.

I appreciate any help.

Well, in Linux, in most cases, better (or newer) hardware is equal with new kernel drivers that works (in some cases) but that are not tuned for performance yet...

An FRIENDLY suggestion: never use Linux in hi-tech-bridging hardware if you don't want to be a innocent and unlucky alpha tester.

You want a performance boost at the console? Turn off your framebuffer: set vga = normal in lilo.conf.

If one of your hard drives is a WD Caviar Green, then read the thread we had on them:

May this be related to DMA?

I have downgraded the fb resolution (from 893 to 791). It raised the display speed, but not file copying.

Two are WD Black and the third is Seagate barracuda.

Any other but not SUCH problems I have expected.

One more thing. KDE runs faster.

Also, run top to see if there's a process taking up a huge percentage of your CPU. Or if a very disk-intensive process such as updatedb is running.

Did you upgrade the power supply unit?
