Browser performance issues with Kibana 4

[simmel]

We are experiencing performance issues with Kibana 4 (currently 4.0.2) on two occasions:

• When loading the Kibana 4 page for the first time
• When entering text in the search field

The performance issues is that the whole browser locks up (on OS X we get the spinning beach ball of death and on Ubuntu the browser gets grayed out) and the browser process uses 100% CPU for a while.

Since we haven't seen this issue being reported before and everyone was surprised by my question on IRC we raise this issue. We are willing to devote resources into help debugging this but I have no idea how to debug AngularJS/Kibana so I'll just start with this issue and Chrome 42 JavaScript CPU profiles for loading Kibana and for adding textinto the search field.

Looking at your cpuprofile this appears to be a duplicate of #1540. How many fields are in your mapping?

[simmel]

$ curl -s -XGET "http://localhost:9200/logstash-$(date +%Y.%m.%d)/logs/_mapping?pretty" | grep -c '^          "'
882

Is that many? Any idea where the pain starts?

Indeed duplicate of #1540, we're working to improve the situation
