Slow system. :/

I remember my arch being uber-fast. But something have chagned. And I don't know realy what. Me KDE is not so responsive as it was, I can feel how slowly khtml renders pages and even new pacman that is rewriten seems slower than it was.

I am suspecting that SATA change has degradated disc performance that wasn't even good in the past since my laptop has painfuly slow disc. But now - everything is awfully slow. I'm quite powerful user, but I'm out of ideas.

Please share with my some advices what could be possibly wrong. I have installed plain KDE (removing kdemod) but I'm still now happy. I can't do anything useful with hdparm because of SATA. What to do? sad

I've tried different kernels (-ck is my favorite), but this has nothing to do with it. I'd glady tried new -ck kernel, but arch package is not ready yet.

Re: Slow system. :/

That's true. I thought it was just me but my kde, in fact, all the desktops are slower recently.
kde 2.5.7 keeps crashing now.

Re: Slow system. :/

Well, it's not affecting me anyway...

Can i suggest you compare lspci and lsmod output?

glxinfo | grep direct

might also be helpful.
Check for issues in kernel init in dmesg.

What is you system specs?

Re: Slow system. :/

in fstab do you have "noatime"  option?

/dev/sda2 / ext3 defaults,noatime  0 1

read here

noatime gives quite a performance boost on any drive

Re: Slow system. :/

Acer Travelmate 243 (2.6Ghz Pentium Celeron IV, 512MB RAM, slow lap disc)

I have DRI enabled. I will turn on atime on my / , but that's not the case - I have been always using atime  and I knew about it.

http://pastebin.archlinux.org/3375 <- dmesg
http://pastebin.archlinux.org/3376 <- lspci

I'm removing qt-enhanched (I've forgot about it when removing kdemod) now.

Re: Slow system. :/

Actually it feels like it was some software problem. Maybe konquror/khtml/qt. Me CPU usage is 100% for a loooong (up to 10 s.) time when sites are being rendered.

Re: Slow system. :/

I found this interesting;

SMP mptable: bad signature [0x0]!
BIOS bug, MP table errors detected!...
... disabling SMP support. (tell your hw vendor)

Can you see both cores? Maybe you dont even have a dual core cpu?

cat /proc/cpuinfo

You could try following the advice it gives you here;

Local APIC disabled by BIOS -- you can enable it with "lapic"

Maybe you should consider updating your BIOS?

Re: Slow system. :/

SMP in BIOS is disabled on TravelMate 243. This is not a bug - this is how they did it. big_smile I have only one core anyway. smile

I will try lapic. Thx for the hint.

I have found problem though /etc/hosts ... was ... overwitten somehow (when beta pacman were here?). Lame not to check that. I've appended my hostname to 127.0.0.1 and I feel a little differenece (or just placebo). I have to work with this some time to know if it's comfortable right now.

I'm still getting impression that khtml in konquror is rendering pages for too long.

Re: Slow system. :/

Check if your loopback interface is running. Run ifconfig and make sure the 'lo' interface is there. If not you need to edit your rc.conf and make sure lo starts at boot.
