RobotStudio event

How can I excute PC SDK faster less than 1ms

Use following code will cost about 40ms. How can I reduce to less than 1ms?

public bool SetPersAllRotTarget(RapidData data, string newValue,int index)
        {
            if (data != null)
            {
                try
                {
                    //RobTarget type = (RobTarget)data.Value;
                    RobTarget type = new RobTarget();
                    type.FillFromString2(newValue);
                    data.WriteItem(type, index);
                }
                catch (ThreadAbortException tae)
                {

                }
                catch (Exception ex)
                {
                    if (abb.LogShow != null)
                        abb.LogShow(ex.Message);
                    MessageBox.Show(ex.Message, "错误", MessageBoxButton.OK, MessageBoxImage.Error, MessageBoxResult.OK, MessageBoxOptions.DefaultDesktopOnly);
                    return false;
                }
                return true;
            }
            else
                return false;
        }
