Description
Sysbench read workload was run on graviton c6g instances, and the performance was not good.
From analysis of the flame graphs of teh runs, it seems __pread call from yb::PosixRandomAccessFile::Read taking lot of time on c6g when compared against c5 flame graph.
This is also reflected in our disk usage pattern. The disk utilization on c6g instances is a higher.
