6 perf-diff - Read perf.data files and display the differential profile
11 'perf diff' [baseline file] [data file1] [[data file2] ... ]
15 This command displays the performance difference amongst two or more perf.data
16 files captured via perf record.
18 If no parameters are passed it will assume perf.data.old and perf.data.
21 specified perf.data files.
24 As the perf.data files could come from different binaries, the symbols addresses
25 could vary. So perf diff is based on the comparison of the files and

160 	For example, we get the timestamp information from 'perf script'.

170 	It analyzes the perf.data.old from the timestamp 3946.361400 to
171 	the end of perf.data.old and analyzes the perf.data from the
172 	timestamp 3971.150589 to the end of perf.data.
191 The comparison is governed by the baseline file. The baseline perf.data
