Disk balancing - when

[oliver.wenzel@xxxxxxxxxxxxxxxxxxxxxxx]

Hello,

we are running a 620 at V4R3 with about 67GB of DASD (mirrored) in ASP1 in
16 pairs of 4GB drives (6607).
Currently, we are at about 80-85% load - growing. 
Performance-wise, is there any use in running DSKBAL ? All units have the
same %used factor.

As another performance issue, we have some problems with commands like
wrksbmjob, wrkactjob etc. Quite often, they
take a long time to complete (>10 secs). This also happens, when system load
is minimal i.e. no obvious reason for the 
slowdown.

We are running AUTOTUNE, so system pools etc. should be fine...

Here's a screenshot of wrksyssts:
