market replay slowing down after a while (b21)

[toulouse-lautrec]

Hi,

i have started to notice with b21 that market replay starts to considerably slow the entire Ninjatrader ecosystem down after some random period.
I can even notice it on the crosshair cursor which gets stuck and unfreezes only after a few seconds after moving the mouse.
Pausing replay brings things back to normal.
Any ideas what the problem might be?

Hello toulouse-lautrec,

Do you notice an improvement of performance if you reduce the amount of NinjaTrader windows you have opened?

Does it make a difference if you run less indicators?

I suspect you have too much windows opened that slows down NinjaTrader. Please see the link below for more performance suggestions.
