Thanks for your very useful reply about I/O performance issues in
Genera! I found it very enlightening.
Also, if you want to complain that what you had to do was too
hard, and you'd like tool X to make it easier, that might be
I think that, after everything else you said, this comment really hits
the nail on the head. The real problem is that it's simply too hard.
How would a user new to Genera and Symbolics Common Lisp ever ferret out
all of the necessary information? Perusing the structure of "Reference
Guide to Streams, Files, and I/O" doesn't turn up anything. The closest
entry for Show Candidates "performance" is "Disk Performance" (which
isn't too close).
But I don't think that anything as sophisticated as a "tool" is even
necessary. I think that the one big hole which needs to be filled is
*documentation*. A section called "I/O Performance Issues", perhaps
initially distilled from your fine reply, would go a long way.
[Aside to Symbolics' doc folks: Nudge, nudge, ;-) ;-) ]
