checksum v2 benchmarks

  TEST File: 10GB

  Test Hardware: Ryzen 5600X, 64GB RAM. I didn't make any effort to kill other
  apps or anything, I'm more interested in relative times here.

  Each test performed three times, mean (simple average) time recorded above.
  All times were *very* similar, with no outliers, so should be accurate.
  
  It is noteworthy that the 2nd fastest algorithm on modern hardware, is MD4:

    Algorithm   Time      Speed
  
    SHA-256:    6.71s     1526.08 MB/s
    MD4:        12.43s    823.81 MB/s
    SHA-1:      14.74s    694.71 MB/s
    SHA-384:    18.1s     565.75 MB/s
    SHA-512:    18.2s     562.64 MB/s
    MD5:        18.57s    551.43 MB/s
  
  Under best conditions, @10GB SHA256 can take under 5.5 seconds (1862 MB/s).
  Under those same conditions, CRC32 will take around 21 seconds (490 MB/s).

checksum v1.3.6 benchmarks

These are my own, personal benchmarks which I produce often when testing DLL
code and compile-time switches. Feel free to use my protocol and compare
your own results, even mail them to me!

My protocol:

  * Quiet the system.

      i.e. close web browsers, music players and other non-essential apps.

  * Hash the test file once, to load it into RAM.

      This way, hard drive speeds/interface/fragmentation/etc., will not
      skew the results - we are purely interested in /computational/
      speed.

      The test file is exactly 1GB in size. You need to have at least 1GB
      of free RAM to do hold the file data! And a 1GB file.

  * Hash the file a further three times, recording the time taken, to at
    least 2 decimal places.

      If all goes to plan, the three times will be *very* close.

      You can repeat this step more than once if you feel the numbers are
      being affected by some system event. Repeat/wait until the results
      /become/ very close. This indicates the system is otherwise quiet.

  * Repeat for all algorithms, using both x86 and x64 checksum binaries.

      The differences are "interesting".

  * Calculate the average (mean) time and use this figure to calculate
    the average hashing speed.

      Record that.
