Previous benchmarks ran against various checksum implementations in #1910 ``` BPC Impl J11-1 J11-2 J8-1 J8-2 ------------------------------------------------------ 1048576 pureCRC32 11.469 11.03 11.673 11.27 1048576 pureCRC32C 11.111 10.98 11.955 11.395 1048576 hadoopCRC32C 15.926 16.686 17.126 18.884 1048576 hadoopCRC32 21.064 20.656 19.65 19.343 1048576 zipCRC32 118.338 116.067 113.645 111.888 1048576 zipCRC32C 117.705 131.284 0 0 ``` These are JMH throughput numbers - higher is better. The Java zipCRC* implementations are 10x faster than the pure CRC32. So please take care if we switch any implementations to benchmark again and ensure the new one is actually faster! -- This is an automated message from the Apache Git Service.
