RE: Hosted LPAR performance

This I have not done. So I don't have any data from the old box to compare to.

I will run this query and see what I can see. But this will only work for Batch jobs, correct?

Thanks
Bob

The usual performance recommendations apply, like did you capture performance data before/after to do comparisons?

Did you capture any QHST data to compare job run times?
SELECT
L.FROM_JOB, L.MESSAGE_ID, L.MESSAGE_TIMESTAMP, R.MESSAGE_ID, R.MESSAGE_TIMESTAMP, INT(R.MESSAGE_TIMESTAMP - L.MESSAGE_TIMESTAMP) as YYYYMMDDHHMMSS FROM TABLE (QSYS2.HISTORY_LOG_INFO( START_TIME => CURRENT TIMESTAMP - 2 days
)) AS l
left outer join
TABLE (QSYS2.HISTORY_LOG_INFO(
START_TIME => CURRENT TIMESTAMP - 2 days
)) AS r
on l.from_job = r.from_job
where l.message_id = 'CPF1124' and r.message_id = 'CPF1164'
and l.from_user not like ('Q%')
order by 6 desc;

Subject: Hosted LPAR performance

I just recently switched my users off of our old System i5 520 to a new hosted LPAR.

The old 520 was 600 CPW with 1GB RAM and 175GB DASD. It wasn't lightning fast, but it ran fine for our needs.

The new hosted LPAR is 960 CPW with 4GB RAM and 500GB DASD. A slice of an 8286-42A. Running over gigabit fiber.

My users are complaining the new system is very slow in comparison to the old box. Why would that be?

I'm fairly certain it's not the internet connection: menu travel flows fine, screens switch quickly enough; the cursor moves as expected without delays. It's just when running a longer process - interactive or batch - it takes longer than before.

Further info: we did a slip upgrade in December, and then when we went live, I FTPd save files of our production data and performed manual restores.

Any suggestions of what to look at? It just seems to me that this new machine should be at least somewhat noticeably quicker - but it's not.

Thanks
