In the breaking changes section in ElasticSearch documentation for 6.3 but under 6.0 it's stated: indices.store.throttle.type and indices.store.throttle.max\_bytes\_per\_sec cluster settings and the index.store.throttle.type and index.store.throttle.max\_bytes\_per\_sec index settings are not recognized anymore. indices.store.throttle.type and indices.store.throttle.max\_bytes\_per\_sec cluster settings and the index.store.throttle.type and index.store.throttle.max\_bytes\_per\_sec index settings are not recognized anymore. It's logical to assume these are not recognized in 6.2 as well, is it true? I could not find them in 6.0 documentation if not the case so please clarify. ---

Thanks. I am only getting 60 to 70 MBps on SSDs seem too low. Any thoughts. Should I change the default Linux disk scheduler cfq to deadline or noop as I read cfq was done for disks. I am using RHEL 3.10.0-693.5.2.el7.x86\_64. Does this version have the right scheduler for SSD or should I change? Thanks ---
