Mongod RC11binaries
Environment:
• Single mongod with wiredtiger as storage engine
• Windows 2012
• WriedTiger configured with 1GB cache
• EC2 machine c3.large
Workload:
• Used hammer.mongo to do insert only workload
Issue -
During insert only workload it's appear that high resolution counter which responsible to notify if operation take longer then X (100msec default) consume ~17% of execution time (see profiler output in the bitmap)
When the default of 100 msec logging, it doesn't justify using this expensive call counter, we should consider cheaper alternative such GetTickCount()
