[slime-devel] slime-streams overhead

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? -T.
