Merge #11517: Tests: Improve benchmark precision
760af84
Removed CCheckQueueSpeed benchmark (Martin Ankerl)00721e6
Improved microbenchmarking with multiple features. (Martin Ankerl) Pull request description: The benchmark's KeepRunning() used to make a function call for each call, inflating measurement times for short running code. This change inlines the critical code that is executed each run and moves the slow timer updates into a new function. This change increases the average runtime for Trig from 0.000000082339208 sec to 0.000000080948591. Tree-SHA512: 36b3bc55fc9b1d4cbf526b7103af6af18e9783e6b8f3ad3adbd09fac0bf9401cfefad58fd1e6fa2615d3c4e677998f912f3323d61d7b00b1c660d581c257d577
