Techinfo is too slow. On a mostly idle RT with a lot of memory and
fast disks, I ran a test where I typed "techinfo" and quit as soon as
I had a prompt. This took 27 seconds (8.1 user + 3.5 system) the
first time and 21 seconds (7.7 + 2.5) the second time. This is too
long.
The RT version was compiled without optimization, and it was compiled
with gcc. Both of these are bad. gcc on the RT is unreliable, and
produces very bad code without optimization. Even with optimization,
it does not do as well as cc.
