A comparison of the feature sets for a handful of terminal emulators was
the subject of  a recent article; here I follow that up by
examining the performance of those terminals.  

This might seem like a
lesser concern, but as it turns out, terminals exhibit surprisingly
high latency for such fundamental programs. I also examine what is
traditionally considered "speed" (but is really scroll bandwidth) and
memory usage, with the understanding that the impact of memory use
is less than it was when I looked at this a decade ago (in
French).
