Hi and thanks for your reply!

If this is the only way to influence this, maybe the default settings
for the niceness of interactive and non-interactive tasks are not the
best choice. (Maybe a distribution problem in this case)

But how does this explain the seconds-long delays?

If an interactive process causes a lot of seeks because of reads/writes
which "are sync", I see how this can greatly slow down otherwise
pipelined write operations, but the other way around?
