Description
Observing significant drop in cbbackupmgr backup throughput from 274 MB/sec to ~145 MB/sec in mad-hatter build .
This performance degradation is consistent in mad-hatter builds after 6.5.0-1562 .
However we are not able to nail down absolute build where this degradation started since there are also intermittent failures due to "concurrent map read and map write " issue in 6.5.0-1563 build (Issue MB-31895) .
Please take a look at the attached logs from affected tests for analysis
