-----------------------------------
Shepherd: Benjamin Mahler
> optimize slave ID comparison in filter lists

> Key: MESOS-3052

> Project: Mesos

>
> With a large number of frameworks that all refuse offers permanently, the
> filter lists can get long. Comparing the slave IDs on the long filter lists
> ends up taking noticeable time.
> Since each filter list traversal matches on on a single slave ID, we can
> optimize this by hashing the slave ID and checking the hash before comparing
> the full slave ID. This is a 5% - 10% performance win.
