Hi All,

I have created two clusters in elasticsearch. When I try to do some search operations in their respective Kibana , it is working as expected.

I have connected cluster 2 as remote cluster of cluster 1. I am trying to run any search query on cluster 2 from kibana of cluster 1, it is taking lot of time sometimes. Can anyone suggest, how to improve it's performance.

If they are remote, what does that mean - same country?  
How large are the clusters?  
How big is the data you are querying?  
What sort of queries are you running?

The output from the `_cluster/stats?pretty&human` API from each cluster might be helpful here too.

Hi @warkolm : After upgrading ELK cluster to 7.10.2 it is working absolutely fine. Looks like there were some issues with v7.7
