Need to Improve performance on finding & retrieving eventframes

We need to find Eventframes generated for last 21 days and retrieve the attributes (nearly 10) for those. For that we are using FindEventFrames PI-SDK method with the startTime parameter as "t-21d" and getting around 40K event frames in the elapsed time of 9min. This is currently taking a lot of time and we need to improve performance a lot. Please suggest us improving performance, by which methods we need to choose for that.

Code used for finding and retrieving eventframes.


var eventFrames = AFEventFrame.FindEventFrames(
                      database: afDatabase,
                      searchRoot: null,
                      startTime: "t-21d",
                      startIndex: 0,
                      maxCount: int.MaxValue,
                      searchMode: AFEventFrameSearchMode.ForwardFromStartTime,
                      nameFilter: "",
                      referencedElementNameFilter: "",
                      elemCategory: null,
                      elemTemplate: efTemplate,
                      searchFullHierarchy: true);


          foreach (AFEventFrame ef in eventFrames)
                    var val1 = ef.Attributes["AssetGlobalUniqueId"].GetValue();
                    var val2 = ef.Attributes["EventDefinitionId"].GetValue();
                    var val3 = ef.Attributes["DetectorId"].GetValue();
