James Howe commented on COUCHDB-1791:
-------------------------------------
On [~rnewson]'s suggestion I tried increasing view_checkpoint_interval to 1000
(to match the compactor), but this had no effect on the index size or time
taken.
> Initial index of views is highly fragmented

> This view, running on CouchDB 1.2.1, takes 16 minutes to index from scratch
> on an inactive database, creating a 2.5GB file.
> After compaction, the file is then only 157MB.
> Can we do something about this waste of disk I/O, such that the initial index
> is smaller to start with?
