[slime-devel] slime-streams overhead

[Tobias C Rittweiler]

Compiling swank.lisp via

  (time (compile-file "swank.lisp"))

vs

  (time (compile-file "swank.lisp" :verbose nil :print nil))

reveals a major overhead.

First command takes ~14secs, whereas the second 2.3 secs.

The first command at the terminal, without Slime, takes
roughly 5.5 secs.

Using :spawn, without dedicated output stream. Dedicated
output stream probably has a much better performance,
but where does /that/ much overhead come from in the default
implementation?
