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?

Have you tried the -mm tree yet ?
If not you should.

Hi,
I also have problems with speed under 2.6 ...
However, disk I/O is slower under 2.6 ... comparing to 2.4.
I talked to some people about it .. and they have the same experience ...
Aksed once about that on this mailing list, but didn't get answers ...
Regards
S

Install oprofile and do a profile run on the 2.6 kernel. This should
tell you where the system time is wasted. Post the results on this
list.

Try mounting your reiserfs filesystems with the `-o nolargeio=1' option.
If that doesn't help, please run a comparative kernel profile. See
Documentation/basic_profiling.txt.
Thanks.

I'll do this next.

You might also want to try 2.6.5-rc2 which has a set of reiserfs fixes
from 2.4.x. 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).

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.

Andreas Hartmann

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)

Spending a lot of time on do_softirq() while compiling stuff is peculiar.
What device drivers are running at the time? disk/network/usb/etc?

No. I mean which drivers were actually doing significant amounts of work
during the test?
(you appear to not have any disks)

Surely do I have disks - I forgot them :-). 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:
