Task history takes too long to load on remote server for small number of logs

TaskEventLog takes really long time to load logs for a particular task even for small number of logs.

I am using TaskEventLog constructor to connect to a remote server to read logs/history of a task. The code takes really long time to finish even for a small number of logs (30-60 entries). I am not getting any run time exceptions so I think that the creation of TaskEvent object is taking long. Please find below the code and other details.

• Library Version - 2.8.16
• Remote Server - Windows Server 2016 , 64-bit, x64 based processor

Any help/suggestions to resolve this issue is greatly appreciated.

TaskEventLog log = new TaskEventLog(@"\Test Task",
                // Specify the event id(s) you want to enumerate
                new int[] {
                    200 /* ActionStart */,
                    201 /* ActionSuccess */ ,
                    202 /* ActionFailure */
                },
 // Specify the start date of the events to enumerate. Here, we look at the last week.
 DateTime.Now.AddDays(-7), "Server", "Domain", "Username", "Password");

// Tell the enumerator to expose events 'newest first'
log.EnumerateInReverse = false;

//The below code takes long time to finish (more than 5 minutes for 50 odd logs)
var history = log.Select(ev => new History
                {
                    Level = ev.Level,
                    Created = ev.TimeCreated,
                    EventId = ev.EventId,
                    TaskCategory = ev.TaskCategory,
                    OperationalCode = ev.OpCode,
                    CorrelationId = ev.ActivityId
                })
                .ToList();

//Custom class for displaying History on the UI
public class History
    {
        public string Level { get; set; }
        public DateTime? Created { get; set; }
        public int EventId { get; set; }
        public string TaskCategory { get; set; }
        public string OperationalCode { get; set; }
        public Guid? CorrelationId { get; set; }
    }

Yes, this surely is a Microsoft issue. However, I noticed that the same code performs better (much quicker) when deployed to some of our environments (DEV & TEST) so I think it is really slower on my work computer (may be some restrictions/security things I haven’t figured out yet). I appreciate your time and all the help with this. Thank you!

I have the same issue. Please could you tell me whether you have found the reason of your performance problems?

Unfortunately I could not find any solution to fix the performance issue, however, there was a significant performance improvement after the application was deployed to server. I was facing this issue on my workstation.
