> History UI: Taking over 1 minute for initial page display
> ---------------------------------------------------------

> Key: SPARK-21254

> Project: Spark
> Issue Type: Bug
> Components: Web UI
> Affects Versions: 2.1.0
> Reporter: Dmitry Parfenchik
> Priority: Minor

> Currently on the first page load (if there is no limit set) the whole jobs
> execution history is loaded since the begging of the time. On large amount of
> rows returned (10k+) page load time grows dramatically, causing 1min+ delay
> in Chrome and freezing the process in Firefox, Safari and IE.
> A simple inspection in Chrome shows that network is not an issue here and
> only causes a small latency (<1s) while most of the time is spend in UI
> processing the results according to chrome devtools:
