Hi Alan,

I'm using normal (7.200 RPM) HDDs. But, as pointed out in
my mail, there is only one job running ("despooling Attributes") at the
moment. All other jobs are still waiting for execution ("waiting on
max storage jobs").

On the SD there are about no IO-Operations. iotop shows some 100KB
once in a while. CPU is 100% idle, same on the Director.

The MySQL-Machine writes more or less constant 450KB/sec. to disk
(mysql process). top shows about 20% wait and 76% idle.

So it shouldn't slow down things that much.

Doesn't it?

Thanks.
