+.SH PERFORMANCE
+There are several ways to fine-tune t-prot's performance:
+.PP
+Some command line options are quite grave a performance hit -- do not
+use -k and especially --ms-smart if you are content without them.
+.PP
+Checking for special footers is very costly as well. Put as few footer
+files as absolutely needed in any footer directory.
+.PP
+All PGP related options are eating up lots of CPU time. Try to avoid them
+on unsigned and unencrypted messages.
+.PP
+When calling t-prot from within mutt, you might use mutt's folder-hook
+and message-hook facilities to turn options on only when needed, e.g. to
+set up a different footer directory for each mailing list folder.
