This concern about performance seems unreasonable to me.

Yes, faster HW will be faster.

But the port to x86 was never about performance.  It was to keep VMS 
usable in the future.  Why?  Because everything on which VMS ran, with 
the exception of emulators, is either dead, or in one case sinking.

People still using VMS are doing so for a reason, and x86 VMS offers 
them a way forward.
