Sylvain Lebresne commented on CASSANDRA-3772:
---------------------------------------------
I suppose that we'd want to tweak the stress params so that each indexed_slice
call returns more results (so that each call end up doing more hash
computation). However if we have to tune too much to get even a slight
improvement, I wonder if it's worth bothering with that.
Btw, did we micro-benchmarked our version of murmur3 against md5? How much
faster is it?

> MD5 is a relatively heavyweight hash to use when we don't need cryptographic
> qualities, just a good output distribution. Let's see how much overhead we
> can save by using Murmur3 instead.
