I'm sorry but I forgot something...

5. Assuming (let's say) M68040-class IOCs, what is the fastest loop that one
   would normally close via database processing, ie via some sort of

   input record   --->   algorithm record   --->   output record

   chain? I just mean a ballpark figure. 1 Hz? 10 Hz? 20 Hz? Presumably one
   needs to consider two cases:

   a) all above database records on same IOC
   b) database records distributed across more than one IOC

   How much is the answer influenced by scan task priorities (assuming that
   CPU is not a scarce resource)?
