Slow filesystem on Saga

Several users have reported slowness and poor performance on the Saga filesystem after the recent maintenance stop. We’ve been investigating, and found a likely cause in improper tuning parameters being set.

We are working on correcting this as soon as possible. Thank you for your reports, and sorry for the inconvenience.

UPDATE Nov. 9 15:26 CET: We have identified a likely root cause of the issue, and corrected it. The performance should now be back to what it was before the scheduled maintenance. We will continue our investigations to improve the service even further.
