Really Slow Performance in 12.0
 
Hi folks,
I do have some severe problems regarding performance in Slackware 12.0. The system responsiveness is really low, booting is a horror and app starting too (i.e. akregator takes almost 4 Minutes to start up!).
Now I've traced it back to a kernel problem. There's some feature activated in 12.0, which has not been activated before. I already tried several things, but couldn't find the right one. It's definitely not (only?) dynticks, hrtimers or HPET. APIC might be, but I can't unselect it, it's needed by another option.
Anybody any idea?
Thanks in advance

What about a sluggish driver or something like this?

ppr:kut 07-24-2007 04:22 AM
I can't think of any driver causing this. See I had a working 2.6.19 kernel in 11.0, but forgot to back it up. Now I have trouble finding an option even in 2.6.19 to kill this responsiveness bug. I can't think of any driver running, which I haven't used also before.

Slelect the timer to be 300 HZ instead of less.
1000Hz is also a good choice
disable the tckless option too
disable all unneeded modules, eventualy enable the empty categories so jou cn compile them later in ;-)
without changing the bzimage...
disable preemptive (no force d preemption) as this is known to make problems sometime,
jet still enable preempt the big kernel lock...
What's Your CPU/MoBo?

Alien Bob 07-24-2007 06:29 AM
I had this once when my SATA drive was detected as a IDE drive (this is entirely possible with current hardware that uses bridged SATA to IDE). The IDE driver grabs hold of the device and asa a result, DMA is never turned on. You are also unable to turn it on.
Let's suupose your drive is called hda.
Look at
Code:
hdparm /dev/hda
if your hard drive is detected as hda and check the status of the DMA. If it is off, and
Code:
hdparm -d1 /dev/hda
refuses to turn it on, then you have the problem I described where your disk should be using the SATA driver but instead is using the IDE driver.
This is not trivial to solve (apart from re-installing Slackware).
The kernel needs a parameter "hda=noprobe" so that the SATA driver gets a chance to probe the hardware. If that succeeds, your drive will become sda.
In /etc/lilo.conf, you would need an additional line:
Code:
append = "hda=noprobe"
The problem with an already installed system is that when hda changes to sda, your /etrc/lilo.conf and /etc/fstab (and possibly other files) will contain the wrong device names, and your Slackware will no longer start. You will need to do a "rescue boot" using the SLackware CD or DVD and fix the fstab and lilo.conf files.

At Alien Bob:
I do have dma (sometimes at least..., depending on the kernel version I use).
My hdd is definitely ide, not sata, so calling it hda, might be accurate ;)

At SCerovec:
I have normally 1000Hz enabled, when I use my self-compiled kernel. Don't know what Slackware has enabled by default though. dynticks is disabled, as well as the high resolution timers, and the high precision event timers (HPET).
"Preempt the big kernel lock" is enabled, but I will try to unselect preemptive, although I never had problems with that.

Info:
My CPU is a Intel Pentium 4, 2,53 GHz (Single Core ;) and I have 1GB RAM
Should run fast as hell ;))

bioe007 07-24-2007 10:42 AM
so for the basics..

what does 'top' show ?

have you done:
Code:
diff -u <mykernel>.config <PV>.config > config.diff
? this can be very enlightening.

what CPU governor are you using?

whats your memory usage like?

swap? what is your swappiness set to?

are all your bus devices recognized? (lspci -v ?)

is your lapic working? (dmesg | grep lapic) (if you have one)

SCerovec 07-24-2007 11:59 AM
I would try a config from slackware 11.0 as default (2.6.18?)
From there I would build the kernel
Regarding Your CPU/MoBo I would check the lapic in the BIOS setup (1.1/1.3/1.5) an the apic=off acpi=off|ht or nolapic boot parameters too
Did you try the intel's tool ? What does it find?

ppr:kut 07-26-2007 03:49 AM
So I reconfigured the kernel with the configuration of 2.6.18 (Slack). Found a ISA/PCMCIA Bug, which I fixed. Now the system is a little bit faster than before, but still unusable.
lspci finds the same devices as under 2.4 and I can't find any usable in dmesg.
Memory is almost unused, Swap space is totally empty.
LAPIC is on, I'm trying now to turn that off, and I'll look if the "routeirq" stuff can also fix some things.
Via Top I found, that there's nearly no process blocking cpu. My Processor has almost nothing to do.
Also, from a visual point of view, it seems as if the system slows down right before init starts.
BTW, SCerovec, with Intel's tool, did you mean powertop?

ppr:kut 07-26-2007 04:18 AM
Neither routeirq nor nolapic did have any impact.
Somehow I could neither get no-apic (noapic, apic=off) nor no-acpi (same stuff as before) working, any ideas?

For the possibility that anybody else can find something I will post the dmesg here:

Could there be any chance of a bad block on the HDD?
Please run any check possible before scratching this one (i do work in a PC service and is sad how easy HDDs develop bad-blocks these days)

dvb-ttpci: could not load firmware, file not found: dvb-ttpci-01.fw
dvb-ttpci: usually this should be in /usr/lib/hotplug/firmware or /lib/firmware
dvb-ttpci: and can be downloaded from http://www.linuxtv.org/download/dvb/firmware/
never seen that - doesn't look good, but maybe irrelevant ?

what about the other stuff i asked?

mem/swap

also try
Code:
hdparam -t -T /dev/hda
hdparm -I /dev/hda # can also use -i
you might also try looking at these from both runlevel 3 vs. 4 and see if something in your desktop is hogging resources.

The hdparm option '-I' for getting information direct from device. The hdparm option 'i' is for information at boot from device.

Somehow I could neither get no-apic (noapic, apic=off) nor no-acpi (same stuff as before) working, any ideas?

For the possibility that anybody else can find something I will post the dmesg here:
Looks to me like you have a dvb tuner in you computer or maybe one connected via a usb hub.
I'd pull the tuner out and also disconnect any usb devices and boot like that.
Than start connecting stuff gradually one piece at a time and see which one causes the trouble.
I had my dvb tuner crash xorg yesterday, locked up both keyboard and mouse.
Had to reboot the computer via remote ssh connection.

It's definitely some hardware that's causing it.

So. I've taken the config of a Slack 10.2 2.6.13 kernel, and based on that I got a fully working kernel image. (Hurrraaaaayyyy!!!!!)
From first impressions (and diffs ;)) it seems as if APIC was the cause. I must have missed some options in the config somehow, and the boot parameters must have not worked.
I'll post again if I'm totally sure.
Thanks all of you!
