Subject: [PATCH] Adjust splitsize:

benchmark                         old ns/op     new ns/op     delta
BenchmarkEncode10x2x10000-2       243613        229413        -5.83%
BenchmarkEncode100x20x10000-2     23041318      19311104      -16.19%
BenchmarkEncode17x3x1M-2          54469780      49602836      -8.94%
BenchmarkEncode10x4x16M-2         674538600     647037000     -4.08%

Bigger sizes (1024) yeilds slower less speedup.
