Subject [jira] [Created] (SOLR-3094) The statistics entry on the new admin UI is very slow

The statistics entry on the new admin UI is very slow

                 Key: SOLR-3094
             Project: Solr
          Issue Type: Bug
          Components: Schema and Analysis
    Affects Versions: 4.0
         Environment: trunk only, all environments
            Reporter: Erick Erickson
            Assignee: Erick Erickson

Prompted by Robert Reynolds (SOLR-2667), the entry point in the new Admin UI core drill down
(e.g. clicking "singlecore" takes a long time. 28-46 *minutes* on a 13M-23M doc set.

On an example Wikipedia index (11M) docs, I see 21 seconds, compared to less than 2 seconds
in the old admin UI (I'm using the old admin UI linked to from the new UI page on trunk).
I have a very simple index layout compared to a commercial site. Clearly something is not
right. I suspect that all the terms are being walked.

This is particularly an issue because this behavior happens when I click "singlecore", so
getting to the really neat parts of the new UI is hard.

Robert reports on a separate thread that the same behavior happens just hitting admin/luke
in the URL which is also slow in the 3.x world, which hints at where the problem lies.

I'm going to guess that the terms are being walked and we can use the tricks used in SOLR-1931
to deal with the fact that admin/luke takes a long time, and just change the call to the entry
("singlecore") for this issue.

Robert: Thanks for pointing this out!
