Hello!
I tested kernel 2.6.4. While compiling kdelibs and kdebase, I felt, that
kernel 2.6 seems to be slower than 2.4.25.
So I did some tests to compare the performance directly. Therefore I
rebooted for everey test in init 2 (no X).
I locally compiled 2.6.5rc2 3 times under 2.6.4 and under 2.4.25 on a
reiserfs LVM partition, which resides onto a IDE HD (using DMA) and got
the following result:
In the middle, compiling under kernel 2.6.4 tooks 9.3% more real time than
under 2.4.25.
The user-processortime is about the same, but the system-processortime is
under 2.6.4 32.9% higher than under 2.4.25.
Now, I switched off preemption. But the performance isn't much better:
8.8% (9.3% with preemption) more real-time compared to 2.4.25 and 28%
(32.9% with preepmtion) more system-time.
Does anybody know, how to get the same performance under 2.6.4 (or even
better) as under 2.4.25?

I'm hoping those will clean things up for you. 2.6.5-rc2-mm3 and higher have a number of other reiserfs performance fixes, but most of those were not in 2.4. Trying them out will complicate the picture (although I'm still interested in numbers from -mm). -chris ^ permalink raw reply [flat|nested] 15+ messages in thread

I'm hoping those will clean things up for you. Ok, here is the result for 2.6.5-rc2 (3 times middle, with preemption), compared to 2.4.25. The result is, the performancedifference to 2.4.25 is the same as for 2.6.4 as described above. Nearly means: The real processing time is about 1% faster than under 2.6.4, but 8.3% slower than with 2.4.25. The system-processortime is 1.2% faster than under 2.6.4 but 31,7% more than under 2.4.25. The times for the user-processortime is unchanged. But I'm not shure if these values are really significant, because the values for the real time meassured each try differ a lot under 2.6. For example 2.6.5rc2: between 9.07 min and 8.37 min for real time. Under 2.4.25, the differences are a lot of smaller: between 8.06 min and 8.15 min for real time. The values for user and system time are nearly constant with 6.49 min and 36 sec (kernel 2.6) and 6.43 min / 27 sec for 2.4.25.

Trying them out will > complicate the picture (although I'm still interested in numbers from > -mm). Now, I tested 2.6.5-rc3-mm4. Same procedure. The good news first: 2.6.5-rc3-mm4 is nearly as fast as 2.4.25 - it is about 2% slower than 2.4.25 (with preemption turned on). Now the bad news: The system-processor-time is unchanged abnormal high: it is 34% (!) higher than in 2.4.25 (and about 1% more than in 2.4.6). Btw: Did the other profile outputs help to find the problem? These are the profile-values for an example run (make of kernel 2.6.5rc2) with 2.6.5rc3mm4: 48344 default_idle 1007.1667 2 cpu_idle 0.0312 1 exit_thread 0.0156 2 flush_thread 0.0156 2 release_thread

I've got two IDE-HD's, /dev/hda and /dev/hdb. /dev/hdb is switched off during boot with hdparm. On /dev/hda, the whole work is done. There is a cdrom and a cd-writer on /dev/hdd and /dev/hdc. They have been not used during the tests. I think it is best, if I post the whole boot-entries from messages: Apr 2 08:14:56 athlon kernel: PI: PCI Interrupt Routing Table [\_SB_.PCI0._PRT] Apr 2 08:14:56 athlon kernel: ACPI: PCI Interrupt Link [LNKA] (IRQs 1 3 4 5 6 7 10 *11 12 14 15) Apr 2 08:14:56 athlon kernel: ACPI: PCI Interrupt Link [LNKB] (IRQs 1 3 4 5 6 7 *10 11 12 14 15) Apr 2 08:14:56 athlon kernel: ACPI: PCI Interrupt Link [LNKC] (IRQs 1 3 4 *5 6 7 10 11 12 14 15) Apr 2 08:14:56 athlon kernel: ACPI: PCI Interrupt Link [LNKD] (IRQs 1 3 4 5 6 7 10 *11 12 14 15) Apr 2 08:14:56 athlon kernel: ACPI: PCI Interrupt Link [ALKA] (IRQs 20) Apr 2 08:14:56 athlon kernel: ACPI: PCI Interrupt Link [ALKB] (IRQs 21) Apr 2 08:14:56 athlon kernel: ACPI: PCI Interrupt Link [ALKC] (IRQs 22) Apr 2 08:14:56 athlon kernel: ACPI: PCI Interrupt Link [ALKD] (IRQs 23) Apr 2 08:14:56 athlon kernel: IOAPIC[0]: Set PCI routing entry (2-16 -> 0xa9 -> IRQ 16 Mode:1 Active:1) Apr 2 08:14:56 athlon kernel: 00:00:08[A] -> 2-16 -> IRQ 16 Apr 2 08:14:56 athlon kernel: IOAPIC[0]: Set PCI routing entry (2-17 -> 0xb1 -> IRQ 17 Mode:1 Active:1) Apr 2 08:14:56 athlon kernel: 00:00:08[B] -> 2-17 -> IRQ 17 Apr 2 08:14:56 athlon kernel: IOAPIC[0]: Set PCI routing entry (2-18 -> 0xb9 -> IRQ 18 Mode:1 Active:1) Apr 2 08:14:56 athlon kernel: 00:00:08[C] -> 2-18 -> IRQ 18 Apr 2 08:14:56 athlon kernel: IOAPIC[0]: Set PCI routing entry (2-19 -> 0xc1 -> IRQ 19 Mode:1 Active:1) Apr 2 08:14:56 athlon kernel: 00:00:08[D] -> 2-19 -> IRQ 19 Apr 2 08:14:56 athlon kernel: _CRS returns NULL!
