Carlos Fuertes commented on SPARK-2016:
---------------------------------------

The real problem with the unresponsiveness of the browser is with the css style 
used for the tables. I have updated in that same pull request the style of the 
table and that solves the issue without having to modify how the data is 
currently presented (although we could still add any other suggested options). 
See SPARK-2017

> Try run
> {code}
> sc.parallelize(1 to 100, 1000000).cache().count()
> {code}
> And open the storage UI for this RDD. It takes forever to load the page.
> When the number of partitions is very large, I think there are a few 
> alternatives:
> 0. Only show the top 1000.
> 1. Pagination
> 2. Instead of grouping by RDD blocks, group by executors
