First of all, Hand2Note now has its own PostgreSQL server which starts with the application and stops on its shutdown. Therefore, you do not need to use the connection to custom server. Please, uncheck this option and activate or create a new database in Configurator-->Database:

I think, it will solve most of the problems you have described.

There are some general tips to improve performance while building stats in Hand2Note.

  1. Use fresh clean database with the most relevant hands, perform maintenance oftenwith pgAdmin3.exe or create new databases as needed.
  2. Clean your Config. Delete all unused and irrelevant HUD and popup profiles from your config. Check your active popup profiles and delete the least relevant stats and tabs.
  3. Perform stat maintenance in Configuration -> Other options -> Maintenance. This will delete all unused or corrupted stats from your config.

The fewer there are stats and popups for Hand2Note to process, the faster and smoother stats building will go.
