RE: Hosted LPAR performance

Jim

We discussed this earlier in this thread. I do have 6 disks as per WRKDSKSTS. Just not sure yet if they are physical or virtual, SSD, 10K, 15K, or flash. Waiting on that answer from the hoster.

Thanks
Bob

Yea, with only 500GB of storage did the vendor stick you with one or maybe two DASD devices instead of the required 6 units to ensure performance?

Hi Bob,

as a hoster which also provides shared machines, we know these questions.
Depending on the hoster you are working with, there is a lot of
parameters to check out
- CPU should be faster - yes (you might have 0.1CPU of a Power8
- Network usually is no issue
- what about disk performance? Depending on the disk setup they use,
other LPARs might draw too much disk performance

Run a WRKDSKSTS whilst running some programs and check out the last
column which will tell about latency and waits. I assume this might be some issue.

When you did your FTP, can you remember if it was fast or not?

Any suggestions of what to look at? It just seems to me that this

machine should be at least somewhat noticeably quicker - but it's not.
