Panther really, really slow. 2009-03-12

UPDATE 2009-03-16
One of the hard drives in the SAN died on Friday, 3/14. It is likely that this failure contributed to Panther's slowness earlier in the week as it developed. Reports are that performance is much better today.

++++++++++
Panther is being agonizingly slow. No, it's not just you. It's taking many people 15-20 minutes to log in. We are actively working on this. All diagnostics look fine, which is really strange. We've called in the "big guns" (read: external consultants) to investigate on a Priority 1 status, so we hope to have it resolved soon.

Further updates will be posted here.

2008-12-18 Panther server issues update

Panther did not experience the expected slowdown during third hour today. We have noticed a pattern of Thursdays not having the same slow performance as other days. Additionally, it was noted that today the Desktop Publishing Class did not log in, which may be correlated. We are investigating whether the DTP applications are running locally, as they should, or from the server, which would be bad.

2008-12-16 Panther server continued sluggishness

2008-12-16
Panther server for OHS continues to have sluggish response speed, especially between 9:40 - 11:00 AM.

We have eliminated network congestion as a cause.
All health metrics on Panther report being normal: 3-7% CPU utilization, zero NIC errors, average RAM utilization.
Because no errors are being reported by the server's own health checks, we cannot identify the issue to fix it. We are continuing to investigate and are calling in consultants to help.

We realize this is causing lost productivity and instructional time. This is a top priority for the IT staff. We appreciate your patience in this difficult situation. Please continue reporting any patterns you observe.

Thank you.
