52 The record command records samples of the profiled processes in a time period. Here’s how it works:
57 5. Simpleperf reads samples from the mapped buffers and stores profiling data in a file called
327 The record command is used to dump samples of the profiled processes. Each sample can contain
332 what frequency to dump samples, how long to monitor, and where to store samples.
336 # frequency (4000 samples per second), writing records to perf.data.
392 To avoid taking too much time generating samples, kernel >= 3.10 sets the max percent of cpu time
393 used for generating samples (default is 25%), and decreases the max allowed sample frequency when
474 Simpleperf is a CPU profiler, it generates samples for a thread only when it is running on a CPU.
