Notes on Profiling Proof General in XEmacs [da]
------------------------------------------------
M-x clear-profiling-info
Eval: (profile (proof-toolbar-next) (proof-shell-wait))
M-x profile-results
NB: Must ignore calls to accept-process-output and sit-for, these
are from proof-shell-wait (only).
Testing by processing first line of src/HOL/Real/ROOT.ML (i.e. loading
RealDef)
Best case scenarios:
* Running Isabelle in ordinary shell buffer in Emacs, PIII:
~8% Emacs (PIII), ~90% SML if shell hidden
~15% X, ~25% xemacs, ~60% SML if shell displayed!
* Running Isabelle in xterm:
~3% xterm, ~2% X, 95% SML if xterm hidden
~4% xterm, ~16% X, 90% SML if xterm revealed
Before optimization:
* CPU time split about 70%/30% (Cel 366) or 65%/35% (PIII 500) SML/xemacs
Sample Runs. Tue Oct 5
