About 10 years ago, I wrote a C app that would read scores from football games and calculate rankings based on the outcome of the games. In fact, I still use this app. You can view my rankings at http://members.cox.net/jocknerd/football.
A couple of years ago, I got interested in Python and decided to rewrite my app in Python. I got it to work but its painfully slow compared to the C app. I have a file containing scores of over 1500 high school football games for last season. With my Python app, it takes about 3 minutes to process the rankings. With my C app, it processes the rankings in less than 15 seconds. The biggest difference in my two apps is the C app uses linked lists. I feel my Python app is doing too many lookups which is causing the bottleneck. I'd love some feedback regarding how I can improve the app. I'd like to drop the C app eventually. Its really ugly. My goal is to eventually get the data stored in PostgreSQL and then have a Django powered site to process and display my rankings.
