brettlounsbury commented on issue #101: IO-649 - Improve the performance of the contentEquals() methods. URL: https://github.com/apache/commons-io/pull/101#issuecomment-578764319 Hi @garydgregory, I don't see any comments from you other than the request for a benchmark. I have updated IOUtils to include a test dependency on JMH and and to include a benchmark that shows BufferedInputStream.read() performance compared to InputStream.read(byte[]) performance. This test creates an 8MB file on disk once before the benchmark is ran and reads it back in. It then just keeps a running sum of the bytes in the file (and ignores any overflow/underflow) and blackhole's the sum at the end to avoid any compiler optimization. Results look something like this: Benchmark Mode Cnt Score Error Units SingleByteReadVsMultiByteReadPerformanceTest.testReadMultiBytes avgt 25 6220618.290 ± 204562.812 ns/op SingleByteReadVsMultiByteReadPerformanceTest.testReadSingleByte avgt 25 21740409.146 ± 711294.924 ns/op
