      Description

      As analysing the performance of ycsb 100update workload on high performance machines, clock_gettime can degrade the performance in virtualization layer. This call in WiredTiger is called from __wt_epoch (which essentially comes from __wt_session_cursor_cache_sweep call stack) and needs to be investigated.
