Subject: [PATCH] grok-pull.post_update_hook: favor --sequential-shard for HDD
Date: Thu, 13 Aug 2020 08:04:04 +0000
Message-ID: <> (raw)

--sequential-shard offers better performance on HDD than -j0
since the on-disk active set can be kept small (with -j $HIGH_NUM).
--batch-size can also be helpful for systems with much RAM.
