The processing time is now a flat 26 seconds, which sure beats the original 9 minutes!!! To summarize, the three most significant speedups: 1) Only process 20% of the lines based on a quick check of relavency 2) Switch from using 'Date' class to 'Time' class 3) Minimize substring processing Thanks again to all who have helped! -- Glenn Hugh Sasse wrote: > Did they help at all? > Hugh > >
