our team recently switched from ES 1.7 / Kibana 3.5 to ES 2.3 / Kibana 4.5 and we experience a very poor performance of Kibana 4.5 when at least one document in the results is "large".
Let me explain: the query returns only 6 documents, and according to the statistics the runtime was OK:
Query time: 1029ms
Response time: 8514ms
During this time the browser hangs for 1-2 sec. (you can see it on the 3 "bubbles" in the top right) which would still be acceptable.
BUT! Opening (clicking the arrow in "Discover") one of the 6 documents (let's call it "_id:doc1") takes well over 10-20 seconds and Firefox throws an "unresponsive script" popup:
_id:doc1 has 21 fields and the "message" field is 4.8MB (really looong text).
The same query with the same results takes only a few short seconds and opening _id:doc1 happens instantly in Kibana 3.
We tried this with Kibana 4.5.1 under Linux Mint with Firefox 47 and also under Windows 7 with Firefox and Chrome. Chrome usually performs even worse than Firefox.
Does anybody else experience the same problem?
