"painfully slow" sounds like the MacPorts version.
In my experience, the latest XQuartz has inherited this issue, at least xterm
performance is terrible. Jeremy had a notion about what might be causing it,
but I didn't have the time to look into testing out his fix.

Marty Sereno offered the following rubric (that seems to work as far as
slowdown but not my vi problem).

hi
this may be the weird slowdown that happened after 10.10+. One
counterintuitive way to fix it is:
login on local machine
start XQuartz
logout of local machine
re-login on local machine
start XQuartz
[login to remote machine]
I have some tk user interface programs with a large number of buttons and
panels that slowed to excruciatingly slow performance. I spent a long time
trying to figure out where the bug was including recompiling X11 from modified
source. I think it is something to do with MacOS thinking that the X windows
are not visible and thus denying them CPU cycles (app nap). But the only way
to fix it was the logout/login nonsense, which somehow resets a flag somewhere.
The slowdown returns on reboot, and sometimes occasionally for other reasons
presumably due to the phase of the moon . . .
cheers,
