We are using the PBDCtrl ActiveX with C# VS2005 to display .PDI files.
When we have start our application the first time, the .pdi file loaded was taking a lot of time before it was displayed. The acview.exe process was automaticcaly started and was nort closed when we closed our program. When we restart our program, the first .pdi file was loaded very fast. Why was it so long the first time and how can we make it load faster?
Note : We have the same problem with the OSIsoft.PISDK (PISDKClass / slow at first utilisation) when getting data from PI.
