We are experiencing a large number of routing changes in the kernel of one
of our VAX8600 "gateways".  The number of changes has increased dramatically
due to some route instabilities (that are not the topic of this message).

The question is how the number of changes can affect the performance of 
our system?.

We see about 1000 route changes in the kernel in periods of 10 minutes.  This
is as you can see *extremely* high.  But does this degrade the system 
performance at all?.

I also want to point out that this route changes are then propagated to 
other systems (VAX750s).  And all dance at the same rithm.

Any comments about this will be greately appreciated.
