From what I understand this is true. However the 3200 (and MicroVAX 3600)
systems have the 64 Kbyte secondary memory cache.  The 3100 has to survive
with the on-chip cache.  By comparision the VAX 6200 (don't know about
the 6300 and 6400) have a 256 Kbyte secondary cache.

The larger cache sizes in the 3200 can make for better performance
in memory intensive applications.

I personally have noticed that the 3200 that I have with the Wren IV
disk (601 MB) and the DILOG SCSI controller performs quite a bit snappier
than a VAXstation 3100.
