A question about virtual console/tty speed...
In /etc/inittab there are lines which setup the 6 default tty consoles; for
example:
c1:45:respawn:/bin/agetty 38400 tty1
...which I think makes the first screen output data at 38400bps. My question
is whether it is faster or slower for Linux, (or desirable for users in
general), if we increase this number to 115200 or something like that. About a
year back I tried this with another Linux, and had no noticeable ill effects,
and it did speed up the response time.
Judging from general principles and vague ideas about how the consoles work,
it's uncertain whether a such a higher bps rate should speed the system up or
not. On the one hand, 115200bps would seem to require more work, slowing the
CPU down... on the other hand, the CPU probably has to spend more time waiting
for a 38400bps console to finish, also slowing the CPU down. Yet one must be
less work than the other. Is there a good way to measure which is the most
work?
