slow performance on VM guest using avio_lan

[Wayne Moyer]

I have a gusest defined with two interfaces. When the process trnasfer data from an Oracle database server it is running slow. The process is usually in SOCKT wait state. The process take more than twice the time to run on the VM guest verses on a physical server. Is this a know issue with newwork performance or maybe a setup issue. Any direction on how to resolve this issure would be appreciated. Here is some of the details od the host and guest server for AVIO_LAN drivers. By the way there are no other guests active on the host when I am running this process.

HOST:
HP-UX ghphpvmh B.11.31 U ia64 2929472160 unlimited-user license
AVIO-HSSN B.11.31.1003.01 HPVM Host AVIO LAN Software
AVIO-IGSSN B.11.31.1003 HPVM Guest AVIO LAN Software

GUEST:

AVIO-HSSN B.11.31.1003.01 HPVM Host AVIO LAN Software
AVIO-IGSSN B.11.31.1003 HPVM Guest AVIO LAN Software

Shalom,

What is missing here is actual performance data.

Collect some data and see where the problem lies.

You have some evidence of a network problem. What needs to be determined is the root cause.

Bonsoir,

Don't know if it will help to solve your problem, but AVIO drivers are a bit old. You will find more recent AVIO bundles (B.11.31.1103) @ https://h20392.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=AVIO

Also check latest patches from :

- Release notes @ http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c02545643/c02545643.pdf

- Installation, configuration and administration @ http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c02023903/c02023903.pdf

- and also patch set HPVMguest and HPVMhost @ http://www.itrc.hp.com/service/patch/searchHPUXPatchSet.do?BC=main|

I will set up the test and collect the performance data as well as check out the documentation links. Thanks and I will post the results of the test and the performance data.

I attached the performance data.

After using the performance script provided I could see the real issue was not LAN related. The other suggestions on upgrading the AVIO drivers and performance patches were also applied. Thanks for your input.
