The "perftest" utilities (See ib_read_lat(1), ib_write_bw_postlist(1), ib_write_bw(1), etc.) are micro bench mark utilities. Users of the these can use ib_clock_test(1M) to test accuracy of system clock. The ib_clock_test(1M) utility, tests the accuracy of the system clock, takes no parameters and provides the following output: #ib_clock_test Type CTRL-C to cancel. 1 sec = 1.00004e+06 usec 1 sec = 1.00004e+06 usec 1 sec = 1.00004e+06 usec 1 sec = 1.00004e+06 usec 1 sec = 1.00004e+06 usec ...
