The OpenVMS volume INITIALIZE defaults have been utter dross for 
decades, well beyond the /STRUCTURE=2 or =5 default discussion.

The settings made sense for a VAX-11 box running V3 or so and several 
megabytes of memory, with hugely expensive disks with capacities 
measured in megabytes.

Nowadays, not so much.

I'm sure somebody somewhere has an app that can only work with ODS-2 
and not subset ODS-5, though.

This extends out into caching and other areas too, with the performance 
of SSDs over HDDs.

Various of the virtual memory system parameter defaults were overhauled 
at V7.0, but there are many other areas with defaults that are... less 
than optimal.
