Thanks Mykola for the information. But I am not clear what does ‘query class’ means?

I have an update Mysql query which takes around 0.002 secs if I execute directly in MySQL window, but Query analytics windows show latency as 3.02 secs.  
What does this actually means? Do I need to ignore this or need to take some preventive actions?

Also, I have one select query which shows up Load as ‘1.49 k (16.02%)’, how do I interpret this?

Thanks in advance.
