I'm running an optimization on a 1 minute bar database and it takes around 10 hours or so.
I decided to create another database with 5 minute bar data and run the same backtest on it thinking that it would be close to 5 times faster to run my optimizations. It turns out that optimizations running against the 5 minute database for some reason are taking about twice as long! Any ideas why this would be? I've created a new database from my IQFeed datafeed just to check again and the same thing occurs. My trading partner can run the same optimization and he's getting significantly faster results compared with his 1 minute bar optimization. How can I get the speedup that I'm looking for?
