NT8 and Strategy Analyzer. Slow startup & eating memory. Solution found

[drecio]

Hello,

I hope this help people having this issue with Strategy Analyzer: slow loading time and huge memory consumption. I went from 5+ minutes NT8 startup (2-4GB used) to 10-15 seconds (<300MB)

Fast solution: empty this folder: Documents\NinjaTrader 8\strategyanalyzerlogs

I've been suffering some months of slow startups and memory issues regarding Strategy Analyzer window. I've done hundreds of backtests, and it went worse every time. It happened with some NT8 betas and even with NT8 final 8.0.1

- My workspace includes a Strategy Analyzer so I have to wait 5+ minutes for NT8 to launch, it ends up with a 2-4GB memory consumption.

- If I don't save Strategy Analyzer as part of the workspace, then NT8 loads quickly: 10-15s <200MB, but then if I open up an empty Strategy Analyzer window I have to wait again 5+ minutes and NT8 memory rises to 2-4GB.

Such high memory consumption provokes NT8 to hang up and slow up as soon as I run some backtests.

Since June 2016 I have 26700 files in the folder
Documents\NinjaTrader 8\strategyanalyzerlogs

After making a backup I deleted the files in this folder and now I have a fully functional NT8 again: 10-15 seconds loading time (<300MB memory consumption)

Regards.
