HI Team, if you have 1 TS which is using for read and write then its obvisous to see the slowness from disk I/O as read/write both are taking the BW, You should be checking the kuud TS logs if you seeing any backpressure, soft memory exceed, any timeout, ancestral memory these all parameter will tell you if there is overload to TS and you can increase the parameter as needed, Please remmember running 1 TS with 848 tablets is fine but you should atleast have 3 TS so that one TS will not do all the work ...
