Optimizing Index time on elasticsearch

No replica when full indexing

By disabling replica I found the indexing time could be cut more then half the total time. Replica could be added back after full indexing completes.

Make refresh time a bit longer

Refreshing index time using default value (1 second) put quite pressure to io, especially if you indexing quite big data and querying the cluster at the same time. Making the refresh time longer could relief that io bottleneck.
