A few of our power users reported that long-running backtests would sometimes run out of memory. These power-users are the people who often find new trading strategies and so we wanted to work with them to improve the performance of our backtesting tools. Over the past couple of weeks, our senior engineer found that the problem wasn’t in our code, but in one of the popular Python libraries that we use. We found the problem in numpy and numba. The leak was ultimately caused by how we were using these libraries. We made the correction and as you can see from the following chart, it really improved the memory utilization for our trade simulator. The following is the write-up by our senior engineer so that others can learn from our engineering efforts.

Gpython is a Python 3.4 interpreter written in Go. This is the story of how it came to be, how it works and where it is going. This includes a quick run through how an interpreted language like Python/Gpython works with a dip into the Virtual Machine (VM), lexing source, parsing it and compiling to byte code.
