- I think either the machine was overloaded or something was really amiss.
- While certain applications can make telnetting into OS/2 *really* slow,
- most stuff - especially just the command line - should be reasonably fast.
- Unfortunately, many of the slower applications are editors, as they have
- often been written to do screen updates beneath the cover and then just
- issue a VioShowBuf for the entire screen.
-
- What sort of terminal emulation were you using? It's been a while (and
- I'll try it out myself tomorrow in the office), but I seem to remember that
- certain terminal types were much slower than others. I'm pretty sure that
- vt100 was pretty good, but ansi was slower since it lacked the same support
- for scrolling regions that the vt100 has. Or vice versa :-)

-
- I'd go for it. I don't think it would be possible under 1.3 (when this
- stuff was initially designed), but if it could be pulled off under 2.0
- (especially if it supported interaction with the DOS sessions) I think it
- would be great.
