For me, for running lots of short-lived wine processes, the single biggest 
speedup comes from running a persistent wine server. Without any wine 
processes running, run "wineserver -p". That wineserver instance will then 
stay around (until terminated with "wineserver -k"), greatly reducing the 
startup time for each command.
