Description
Environment:
- v3.1.4-pre-
- AWS C4.XL environment
- WiredTiger default configuration
Initial throughput w/ original binaries used to be ~ 10 K ops/sec during the load phase
I removed two timer operations described below and i doubled the throughput and reduce the CPU utilization by 2/3 (60% to 20%)
