RE: RESEND: iostat 2.4 vs 2.6

From: Alan . d . Pearson

A small update to this problem.
The cciss controller is performing around 1300 interrupts/sec on 2.6 during
the dd operation.

I've also updated the kernel to 2.6.6-rc1 and still the problem exists.

Has anyone any ideas what could be wrong ? The cciss driver ?

Thanks in advance
/proc/interrupts is below :

Alan,


This is not goign to lkml, broken mailer...


After just reading through it all...
I guess you checked why the number of interrupts on 2.6.4 is so high?
On 2.4 it is around 500 per second, while around 1300 on 2.6.

Sorry for sending this twice, first time damn email client line
wrapped it !





Hi all,
First apologies for the very long mail, but I trust it has
all the info you require
to assist me !
I'm experiencing HUGE iowait times on kernel 2.6.4 that weren't there
on 2.4.20.
I've got a dual Xeon 2.8Ghz CPU ML530, 2Gb RAM, with a CCISS
controller, with each drive being a RAID0 device.
So I've got 12 ULTRA320 disks available to the OS.


I've done some simple dd tests and include both the vmstat and iostat
for each test on 2.4 and 2.6 below.





dd if=/dev/zero of=/tmp/x bs=1M count=4906 ; sync
dd if=x of=/dev/null bs=1M count=4096 ; sync





On 2.6 the iowait jumps to around 70%, while 2.4 on both tests it is
firmly zero.


On disk read, I'm loosing 30 Mb/sec of bandwidth PER DISK, compared
to 2.4.20.
I've tried using both the deadline and as ioschedulers but no
difference.





Under real conditions (ie our application running which reads from
all the disks simultaneously) on 2.6.4, the system performance is
around 1/3 of 2.4.20)







Summary MB/Sec :


dd if=x dd if=/dev/zero
2.4 64 35.6
2.6 30.34 35.9






Details are below.
Any help greatly appreciated !


Please cc me on any responses !
Thanks in advance,
AlanP
