[Xen-users] Oracle on a classic Physical server Win2k3 versus Oracle on domU win2k3

Hi everyone,

Configuration:

 - dom0 xen 3.2.1 on debian 5.0.2 kernel 2.6.26-2-xen-amd64
 - domU win2k3 GPLPV: 0.9.17

Problem:

I have done a performance test (swingbench) on a physical server on Win2k3 
with Oracle 10.2 Result: I have 30000 transactions per seconds
But with the domU only have 8000 transactions per seconds however the 
configuration is similar.
The physical plateform between Xen server and Win2k3 server are similar 
too. 
So you find it normal ?

Thanks in advance for your answer !

Rémi

Is windows 2003 definitely service pack 2? Anything earlier will really hurt
performance.

What backend are you using for the DomU? Could you post your domU config?

Is GPLPV is definitely enabled? 0.9.17 is pretty old now, please try 0.10.0.130.
you''ll need to uninstall 0.9.17 using the uninstall bat file before you
install 0.10.0.130.

RE: [Xen-users] Oracle on a classic Physical server Win2k3 versusOracle on domU win2k3

Thanks James for the answer,

Yes my Windows 2k3 have sp2 with the last windows update !
I have just finish to test the GPLPV 0.10.0.130, so now i must tested a 
new swinbench with this driver.
This is my domU config file:

#python
kernel=''/usr/lib/xen-3.2-1/boot/hvmloader''
builder=''hvm''
vcpus=2
memory=4096
name=''oracle10''
vif=[''type=ioemu, mac=00:16:3e:ac:ac:ac, bridge=eth0 '']
disk=[''phy:/dev/disk/oracle10,hda,w'']
device_model = ''/usr/lib/xen-3.2-1/bin/qemu-dm''
boot=''c''
nographic=0
localtime=1
usbdevice=''tablet''
keymap=''fr''

RE: [Xen-users] Oracle on a classic Physical server Win2k3 versusOracle on domU win2k3

I just finished the swingbench test with new drivers (0.10.0.130) but
it''s
the same result about 8400 transactions per seconds..
So if you have an idea, i''m listening to you.

Thanks in advance and good week.

While running the test, run "xm top" in dom0. 

How''s the cpu usage? are your cpu cores maxed out? 
What''s using cpu?

Also run "iostat 1" in dom0 (it''s in sysstat package), and
see if you
have a lot of iowait in dom0..

Is the swingbench test disk i/o bound? Or network too?

RE: [Xen-users] Oracle on a classic Physical server Win2k3 versusOracle on domU win2k3

James, Pasi,

Yes it''s just a swinbench on the performance of transactions on a
Oracle
database.
But not a network test.


My CPU is Intel(R) Xeon(R) CPU 5130 @ 2.00GHz, when i test with 
swingbench, my domU is full cpu (near 197%)
The result of iowait with command: iostat 1  -> %iowait = 0.00

Thanks in advance.

Rémi



While running the test, run "xm top" in dom0. 

How''s the cpu usage? are your cpu cores maxed out? 
What''s using cpu?

Also run "iostat 1" in dom0 (it''s in sysstat package), and
see if you
have a lot of iowait in dom0..

Ok so it''s fully CPU bound. 

Then you should measure CPU usage in the Windows guest and figure out
where all the CPU time goes..

Re: [Xen-users] Oracle on a classic Physical server Win2k3 versusOracle on domU win2k3

Yes my windows guest is fully CPU but i thought  to have better 
performance regarding the number of transactions per seconds compared a 
Physical server.
Thanks,

Rémi

Have you tried pinning the guest vcpus to separate physical cores? And
dedicating a separate core for dom0?

Also, did you try with Xen 3.4.1 ?

Pasi,

I just finished the swingbench test with a dedicated CPU but it''s the
same
performance.
When i will have time, I will test on Xen 3.4.1

Re: [Xen-users] Oracle on a classic Physical server Win2k3 versusOracle on domU win2k3

Hi everyone,

Bad news...
I just test with Xen 3.4.1 modules 2.6.26-6, but the performance are far 
from being the same quality with a physical server win2k3
If anyone have another idea..

Rémi



Pasi, 

I just finished the swingbench test with a dedicated CPU but it''s the
same
performance. 
When i will have time, I will test on Xen 3.4.1

Have you tried pinning the guest vcpus to separate physical cores? And
dedicating a separate core for dom0?

Also, did you try with Xen 3.4.1 ?

You really need to profile _why_ it''s slower. you need to measure
exactly _what_ is using the cpu, or causing the slowness.

You need to monitor in dom0 (using "xm top", "iostat 1",
etc) and *also*
in the windows guest, using whatever tools windows has.

Also, why aren''t you running oracle on Linux? would be a lot easier to
debug..

.. not to mention you''d be able to use PV guest, which would give

Indeed :)

Run Oracle on Linux PV guest and it''s much easier to solve and
troubleshoot performance..
