Hello,

 

Thank you for posting in Q&A forum.

High latency can be caused by several factors and even random issue.

1.Please kindly check performance monitor and see if there was any high CPU usage/Disk usage from performance level.

2.Check event log to see if there's any warning or error when the high latency issue arises.

3.Configure and keep a network monitor/performance monitoring for some time. If issue reproduces please check the monitor log and narrow down the issue.

 

I hope the information above is helpful.

If you have any questions or concerns, please feel free to let us know.

 

Best regards，

Jill Zhou
