Andrew, What I like to do is use a couple of time markers:
put the milliseconds into a_milli put the milliseconds into b_milli Start at the top with both together and you should get zero (to check that it is working). Keep moving the b_milli marker down until you find the problem. At the bottom of your code use put (b_milli - a_milli) && "milliseconds" In general, if it takes 2 sec to do something it is probably a loop that can be improved or Windows is starting up a program or looking for something. If you do find the culprit, post the code and I'm sure someone can speed it up for you.

Bootcamp and VirtualBox implementations of windows Xp, Vista and 7 are the same, so its definitely not windows either, it will be my code somewhere! I hadnt thought of compiling the app on a Windows PC, I always compile on Mac so Ill give that a try, thanks Andy On 15 Sep 2011, at 12:52, Roger Eller wrote: > On Thu, Sep 15, 2011 at 7:40 AM, Andrew Henshaw wrote: > >> Hi, >> >> Ive got an application that quite happily runs along at an acceptable speed >> on my Macs, but on Windows systems it seems to struggle. >> >> Im trying to pin down the parts of the code that I need to look at so I can >> work out what is happening.
