Part of the problem is the MacOS itself. My 180 MHz 604e does 750K
keys/sec with Linux, and 500K keys/sec with the MacOS version. The client
could be written to run as fast as the linux version, but your mac would
essentially be locked up while it was running.

AppleScript it. The only problem would be getting the command line args. I
can probably setup some kind of apple event to bypass that if you want
though.

The CPU's are fast... the OS is slow. The powerpc version calls
GetNextEvent every 131K keys, the 68k version every 64K keys, this lets
the Mac at least try to respond to user events.
