In Kibana dev-console, I see a big difference between ES query took time and Kibana ellapsed time. Why ? ![Capture d’écran 2020-10-02 à 10.49.34](https://us1.discourse-cdn.com/elastic/original/3X/a/0/a0a57c6ec38d6d6871a7240f0bd0003fc335a0be.png) ---

Hi @ebuildy - this post is explaining what "took" is measuring: [Query timing: 'took' value and what I'm measuring](https://discuss.elastic.co/t/query-timing-took-value-and-what-im-measuring/9870) In short it's how long the internals of Elasticsearch spent time on the request - everything outside of the cluster (JSON serializing, transmitting data, ...) is not included. ---

Thanks you ! We found latest Kibana (7.9.X) really slower than before, is it normal ? ---

I'm not aware of anything - this might be worth opening an issue in the Github Kibana repo ---

I really cant believe JSON serialization takes more time than the query itself ..... ---

We can confirm, Kibana 7.4 is faster than Kibana 7.9.2. 7.4 is using "\_msearch" 7.9 is using async search, which is horrible (in our case). We setup a 7.4 cluster, reindex data from our 7.9 cluster, re-recreate Kibana stuff, then load page. Kibana 7.4 dashboard is loading 10x faster. Is is possible to disable the new async search? ---

You should be able to switch back to the old way of data fetching by setting `courier:batchSearches ` in advanced settings to true. ---

Thanks you, I will. To illustrate my misunderstand about Kibana timing, here 4 differents timing information: ![Capture d’écran 2020-10-05 à 09.12.55](https://us1.discourse-cdn.com/elastic/original/3X/d/b/dbc026a8a767346fee687716c86bcdf6a6b6c9c4.png) The real ES query takes 600ms, but I receive the result after 5 secondes. ---
