## How does memory usage for sourmash change with k-mer size?

sourmash hashes k-mers into 64-bit numbers, so the size of what is
stored is independent of the k-mer size. The only impact of k-mer size
on sourmash behavior is then more on the biology side - how many
matches do you gain (or lose) with that k-mer size? And do you have a
lot of new k-mers that pop up with a longer k-mer size (e.g. because
of included variation)? These questions must be answered by experimentation
and may be data-set specific.
