hello, i have noticed that when i click Replay on my chartbook, it is now taking about 3-4 minutes to calculate and run. This was not the case about a year ago. I have not changed my chartbook. I am using the 64bit version and have plenty of RAM. The speed to calculate has slowed considerably. Also, Replay will start about 15 minutes away from the time point i originally selected. Please advise.

Reduce the amount of data loaded in the charts.:
High CPU Usage | Inactive User Interface | Poor Performance | Long Time to Load Chart Data | Charts Reloading Often: 30.1 - Too Much Data to Load or Loaded

Also, use a 1 second or higher Intraday Data Storage Time Unit, instead of tick by tick:
High CPU Usage | Inactive User Interface | Poor Performance | Long Time to Load Chart Data | Charts Reloading Often: 30.12 - Intraday Data Storage Time Unit. Historical Data Record Time Frame.

Review the other items on that page:
High CPU Usage | Inactive User Interface | Poor Performance | Long Time to Load Chart Data | Charts Reloading Often

This probably relates to the amount of time to load the chart data:
Also, Replay will start about 15 minutes away from the time point i originally selected
