Agreed: most codecs only go up to 32k or 64k (in fact, Snappy may use
just 32k, not 64k).
Deflate doesn't benefit from above 64k either, nor does lzf.
The only codecs that I think use larger buffers are bzip and lzma;
both of which are typically way too slow to be used for streaming data
So testing up to 64k is usually enough.
