Yes, the most similar one is indeed Selkie.

misa77 and oodle are both supported in turbobench (see: https://github.com/powturbo/turbobench), so it's easy to compare them.

Results on the silesia corpus on the same Intel setup described in the README, using turbobench:

  codec       decode      ratio    encode
  misa77 -0   5309 MB/s   42.64%   58.2 MB/s
  misa77 -1   4332 MB/s   39.65%   54.5 MB/s
  selkie -1   3095 MB/s   43.48%   197 MB/s
  selkie -2   3013 MB/s   41.80%   163 MB/s
  selkie -3   3081 MB/s   39.58%   95.8 MB/s
  selkie -4   3498 MB/s   36.95%   43.3 MB/s
  selkie -5   2607 MB/s   33.58%   2.97 MB/s
  lz4         2530 MB/s   47.60%   373 MB/s

Note: selkie -4 corresponds to the "Normal" level here.

Any chance you can throw lzop into that table just as a reference point?

Added memcpy in here too, same setup as before:

  codec       decode        ratio     encode
  misa77 -0   5302 MB/s     42.64%    58.7 MB/s
  selkie -3   3078 MB/s     39.58%    97.0 MB/s
  lzo1x -1    421 MB/s      47.48%    314 MB/s
  memcpy      12135 MB/s    100.00%   11952 MB/s
