Robert Muir commented on SOLR-1931:
-----------------------------------
why is it still 39seconds? shouldn't tools like this just use statistics and
not enumerate terms or any anything else by default so that they return
instantly?
its 4.0, why not just backwards break and make it fast?
Instead of doing enumerations and stuff, you could display all of the
Terms-level statistics per segment per field:
* uniqueTermCount (# of terms)
* sumDocFreq (# of postings/term-doc mappings)
* sumTotalTermFreq (# of positions/tokens)
* docCount (# of documents with at least one posting for the field)
This would all be basically instantaneous and would give a more thorough
picture of the performance characteristics of the index (e.g. how many
positions).
You could also compute derived stats like average field length etc too.

> The Schema Browser JSP by default causes the Luke handler to "scan the
> world". In large indexes this make the UI useless.
> On an index with 64m documents & 8gb of disk space, the Schema Browser took 6
> minutes to open and hogged all disk I/O, making Solr useless.
