That is the right setting to disable store throttling, but even without throttling writes MB/sec for merges, the merges can still fall behind, leading to index throttling. ES does this to protect the health of the index because too many segments will cause all sorts of trouble.
What IO system is your index on? If you're on spinning disks you could try setting index.merge.scheduler.max_thread_count to 1 since spinning disks struggle with concurrent merges. See http://www.elastic.co/guide/en/elasticsearch/reference/current/index-modules-merge.html Also, do you leave enough (at least 50%) free RAM to the OS for buffering pages? This can make a difference with spinning disks since the OS has more freedom to do read-ahead on the files being merged...
