Jerome already published that numbers in the past, I remeber his 750Mhz CPU
emulating the PDP11..

Nevertheless, it has nothing todo with the question about a VAX for doing
databse development.
Besides of this, the 750Mhz CPU ist not that fast, you can almost emulate
in on an actual PC :-)

You can always play around with it, I've suggesting an older VMS for it
since those machines tend to be small and slow for VMS7.3. You can check
NetBSD too but I had some ugly problems with VS3100s in the past (M38,
M76). I do have a VS4000/90 to, that's a faster one and I've enjoyed DEC
Windows with it. Have an VAX4000/300 repaired too..

It's definitivly more fun to playa with real hardware, but for Software
development or testing I would suggest simh today.
