The memcpy and memset benchmarks return bogus results when iterations > 0 because the iterations value is not taken into account when calculating the final result: $ perf bench mem memset --only-prefault --length 1GB --iterations 1 # Running 'mem/memset' benchmark: # Copying 1GB Bytes ... 20.798669 GB/Sec (with prefault) $ perf bench mem memset --only-prefault --length 1GB --iterations 10 # Running 'mem/memset' benchmark: # Copying 1GB Bytes ... 2.086576 GB/Sec (with prefault) $ perf bench mem memset --only-prefault --length 1GB --iterations 100 # Running 'mem/memset' benchmark: # Copying 1GB Bytes ... 212.840917 MB/Sec (with prefault) Fix this.
