Post From: Back Test Speed

I haven't used Sierra for about a year. Back then I converted my spreadsheets to the new format since it was clear that was the direction Sierra was going in, and began experiencing unacceptably slow back testing speeds. Thought I'd come back and see if this issue has been resolved but I am still experiencing this problem. I use spreadsheet system for trading, have done all the things in your documentation to optimize the back testing but still very, very slow. I realize from request I made in the past about this problem that you aren't big on fixing it, but a couple of things worth noting: I notice Sierra is not using the computer resources that are available. During a back test, I show less than 30% cpu utilization and about 40% of memory being used. Disc utilization is minimal (and I have a solid state disc anyway), so just wondering if somehow you couldn't take better advantage of the resources available. What is the bottleneck causing this back testing to be so slow? As it stands, it takes more than a day to backtest 1 month worth of data. That's ridiculous, and a shame because everything else about your software is so robust and efficient. It wasn't like this with the old spreadsheets, I used to backtest a month and it took a couple of hours not a couple of days. Won't you please help with this?
