MLT Performance Issue with ElasticSearch 1.3.4


ELastic search 1.0.3 was performing better with respect to MLT Api. We are
witnessing decrease in performance when we upgraded to 1.3.4. Any ideas?

Initially we upgraded to 1.3.3 and then we upgraded to 1.3.4. We also tried
setting index.translog.flush_threshold_size to 1gb but it is still slow as
compared to what we had in 1.0.3.
