Yonik Seeley commented on SOLR-264:
-----------------------------------
nextFloat() generates a random int and then does a floating point divide (one
of the slowest operations around).
Instead, use
return rand.nextBoolean() ? -1 : 1;
Or a branch-free version:
return rand.nextInt() >>> 31;
> Support 'random' sort order
