Hi Markus,
increasing read performance during scan operations is one of our 
major topics of the next release. I agree to you that MaxDB could
be much faster than today concerning this topic. 

Implementing another prefetch technic in the kernel is possible 
but it is only one small piece of our strategy to increase scan 
performance deeply.

Regards,

Betreff: 7.6: parallel read?

Is it possible in 7.6 to enable a parallel read from disk? Imagine if the
optimizer has a threashold value (e. g. 10000). When the costs are higher
than this value Servertasks will be used additionally to get the pages from
the disks (as Oracle does). I'm sure this will really give a performance
boost.

Is this implemented in 7.6 or considered to be in later versions?
