Subject Lucene update performance
Date Tue, 09 May 2017 13:24:17 GMT

For a 5.2.1 index that contains around 1.2 million documents, updating the
index with 1.3 million files seems to take 3X longer than doing a scratch
indexing. (Files are crawled over NFS, indexes are stored on a mechanical
disk locally (Btrfs))

Is this expected for Lucene's update index logic, or should I further debug
my part of the code for update performance?

Thank you,
