> In large multicore environments (hundreds+ of cores), the STATUS request may
> take a fair amount of time.
> It seems that the majority of time is spent retrieving the index related info.
> The suggested improvement allows the user to specify a parameter (indexInfo)
> that if 'false' then index related info (such as segmentCount, sizeInBytes,
> numDocs, etc.) will not be retrieved. By default, the indexInfo will be
> 'true' (to maintain existing STATUS request behavior).
> For example, when tested on a given machine with 380+ solr cores, the full
> STATUS request took 800ms-900ms, whereas using indexInfo=false returned
> results in about 1ms-4ms.
