// Performance testing is done only if requested
// by activating disabled tests.
//
// To run the performance tests,
// supply "--gtest_also_run_disabled_tests" flag to GTest.
// The GTest filter may be applied to filter only performance tests.
// Different tests are compiled depending on the build type.
// Generally, debug or non-debug types are recognized.
//
// Reference performance values are taken
// from a computer with the following specs:
//
// Proc Core i7-2820QM
// Ubuntu 16.04 64bit
// GCC 5.4.0
// Boost 1.58
// TCMalloc 2.4
//
// The performance measurements are expected to have some random variation.
// Better as well as worse performance are reported
// as test failures to indicate the change.
//
// NOTE: Running all the tests may take considerable time.
// NOTE: Running tests several times is recommended
