LZNA encode speed addendum

Filling in a gap in the previous post : cbloom rants 05-09-15 - Oodle LZNA

The encode speeds on lzt99 :

single-threaded :

==============

LZNA :

-z5 (Optimal1) :
24,700,820 -> 9,207,584 =  2.982 bpb =  2.683 to 1
encode           : 10.809 seconds, 1.32 b/kc, rate= 2.29 mb/s
decode           : 0.318 seconds, 44.87 b/kc, rate= 77.58 mb/s

-z6 (Optimal2) :
24,700,820 -> 9,154,343 =  2.965 bpb =  2.698 to 1
encode           : 14.727 seconds, 0.97 b/kc, rate= 1.68 mb/s
decode           : 0.313 seconds, 45.68 b/kc, rate= 78.99 mb/s

-z7 (Optimal3) :
24,700,820 -> 9,069,473 =  2.937 bpb =  2.724 to 1
encode           : 20.473 seconds, 0.70 b/kc, rate= 1.21 mb/s
decode           : 0.317 seconds, 45.06 b/kc, rate= 77.92 mb/s

=========

LZMA :

lzmahigh : 24,700,820 -> 9,329,982 =  3.022 bpb =  2.647 to 1
encode           : 11.373 seconds, 1.26 b/kc, rate= 2.17 M/s
decode           : 0.767 seconds, 18.62 b/kc, rate= 32.19 M/s

=========

LZHAM BETTER :

lzham : 24,700,820 ->10,140,761 =  3.284 bpb =  2.436 to 1
encode           : 16.732 seconds, 0.85 b/kc, rate= 1.48 M/s
decode           : 0.242 seconds, 59.09 b/kc, rate= 102.17 M/s

LZHAM UBER :

lzham : 24,700,820 ->10,097,341 =  3.270 bpb =  2.446 to 1
encode           : 18.877 seconds, 0.76 b/kc, rate= 1.31 M/s
decode           : 0.239 seconds, 59.73 b/kc, rate= 103.27 M/s

LZHAM UBER + EXTREME :

lzham : 24,700,820 -> 9,938,002 =  3.219 bpb =  2.485 to 1
encode           : 185.204 seconds, 0.08 b/kc, rate= 133.37 k/s
decode           : 0.245 seconds, 58.28 b/kc, rate= 100.77 M/s

===============

LZNA -z5 threaded :
24,700,820 -> 9,211,090 =  2.983 bpb =  2.682 to 1
encode only      : 8.523 seconds, 1.68 b/kc, rate= 2.90 mb/s
decode only      : 0.325 seconds, 43.96 b/kc, rate= 76.01 mb/s

LZMA threaded :

lzmahigh : 24,700,820 -> 9,329,925 =  3.022 bpb =  2.647 to 1
encode           : 7.991 seconds, 1.79 b/kc, rate= 3.09 M/s
decode           : 0.775 seconds, 18.42 b/kc, rate= 31.85 M/s

LZHAM BETTER threaded :

lzham : 24,700,820 ->10,198,307 =  3.303 bpb =  2.422 to 1
encode           : 7.678 seconds, 1.86 b/kc, rate= 3.22 M/s
decode           : 0.242 seconds, 58.96 b/kc, rate= 101.94 M/s

I incorrectly said in the original version of the LZNA post (now corrected) that "LZHAM UBER is too slow". It's actually the "EXTREME" option that's too slow.

Also, as I noted last time, LZHAM is the best threaded of the three, so even though BETTER is slower than LZNA -z5 or LZMA in single-threaded encode speed, it's faster threaded. (Oodle's encoder threading is very simplistic (chunking) and really needs a larger file to get full parallelism; it doesn't use all cores here; LZHAM is much more micro-threaded so can get good parallelism even on small files).
