Question about latency and response time

Hi, I have 2 question regarding latency and response time in Elasticsearch.

  1. Why on different monitoring clients there are different response time?

For example in Kibana average request time is 700ms:

In Graphana average request time is about ~300-500ms:

In Dynatrace it's about 100-150ms, though I'm not sure if its measure it correctly:

  1. Why response time suddenly changed?

We've average response time in a cluster about 400ms, but after the new mapping update (we added 3 new fields), response time decreased to 100-250 ms, and kept it that way throughout the day.

The next day, the response time increased again

What could cause a decrease in response time after updating the mapping? And why did the response time rise back?

Thanks!
