I've been backtesting ideas, and would like to get some feedback about backtest performance.
I'm using a 3GHz P4 machine with 2GB RAM under WinXP, and when I work on a collection of about 3,700 symbols, the execution time is 20 minutes on the first run, and 16 minutes thereafter. I have configured the database as follows, to ensure that the database is kept in RAM after the first run: On Tools->Data: - In-memory cache size (max symbols): 10,000 - Max megabytes: 1000 On File->Database Settings: - Data source: TC200x/TCNet Plug-in - Local data storage: <enable> When executing, I notice at the bottom on the screen that each ticker retrieval takes 12-16 ms. Is this a normal response time for data that is supposedly being accessed from RAM? Using TuneUp 2009, I confirmed that the memory was not full during the test (42% free). I'm using AB professional v5.2. Can anyone help, or have I misconfigured something? Many thanks, Paul
