Evidence, please, for the conclusion that those particular three
features account for all, or even most, of the difference in performance
you see?

Are those the *only* features present in SunOS but not in your Xenix?
Does your Xenix have TCP/IP support, or NFS, for example?

(For that matter, are you certain your Xenix lacks VM?)
