I need to Increase dashboard performance which contain heavy css ,HTML

[snehal]

Our dashboard contain Heavy css,HTML and heavy  splunk quries.I want to improve the dashboard performance.

1. Is there other way to reduce loading time other than base search and Span?

2.Is using Javascript for css really helps to improve the performance?

If your splunk search is slow because they are expensive , 

in the dashboard :

• maybe look at acceleration of your saved searches
• if you are using datamodels, look at accelerating them and only look at the accelerated data
• If the dashboard is static, maybe populate it with a scheduled search (running on a regular interval)
• if you have several panels on the same page, populated by similar searches, you could use a base search and "post process"  to populate several panels with the same base search results

Optimize the search :

• restrict the timerange
• limit to only necessary indexes/sourcetypes
• improve your fields extractions (if you have slow regexes)
• optimize for map reduce
• increase the number of indexers to scale
