Storage Servers were tuned, so this maintenance is complete.
The servers statistics shows an increase in the worker threads serving users in parallel.
Please report your experience at rc-help (a ticket you have opened already with us).
We will continue to monitor the system.

As many PL users noticed performance of PL/Active Beegfs have been very poor even after we last tuned 12 days ago.
We have been closely monitoring the system and in contact with our support to understand the reason for that. Yesterday, we identified a problem with our configuration. As we were trying to increase the parallelism to serve simultaneous resource requests, we didn't realized that we were doing that on the storage target level where there shouldn't exist many concurrent requests. After analyzing some server statistics and getting feedback from Beegfs support, it became clear what we should be tuning in order to improve performance.
So, we plan to tune the servers again today to allow parallelism across the different storage targets.
The change should be non disruptive.
Please keep reporting your experience with the system especially after the change today as we are interested in verifying the results with today's change.
