I haven't had any speed problems using AppleEvents with MCL (I get a
response from Excel within a second), but I construct the AppleEvents
myself, instead of using the OSA routines (OSACompile and OSAExecute). I
don't have the numbers anymore, but when I tested compiling AppleScript
using those routines rather than creating the AppleEvents directly, the
OSA routines were orders of magnitude slower. If you have a compiled
script that you run frequently, the penalty isn't that much (although
still significant), but compiling scripts is very slow.
