We've been experiencing a few issues which seems to all be caused by the kibana requestTimeout being reached:

- [https://github.com/elastic/kibana/issues/22426:](https://github.com/elastic/kibana/issues/22426:) Adding or removing column in discover view generates "Unable to write index pattern!" errors
- When saving changes in Index Pattern or Visualization, there are "Object was not saved. Error: Service unavailable" errors, although the changes are saved.
- Some occasional " Unexpected token u in JSON at position 0" errors makes me thinks that the answers are sometimes truncated.

Still, I don't want to increase the requestTimeout, as 30s seems quite a reasonable time for a request in a Web Application and changing the value would in the end only work around the issue.

So is there any steps I can take to troubleshoot performance issue and subsequently do some performance tuning in Kibana?

@EldrosKandar what is the current data volume for those requests? What is the time a simple request from the machine where kibana is hosted takes against your elasticsearch cluster?
