Klaus Ma commented on MESOS-5700:
---------------------------------
Did more test based on the Resources benchmark:
1. make Resource's name & role to be enum/int will improve 400ms per 10
operator on 1000 resource.
2. using hashmap in Resources will improve 2 s per 10 operator on 4000
resource; it should be more improved if using name + role as key. The overhead
of hash map is 70ms per 5000 operators on 4 resources.
Please refer to the attachment for the code diff I used.
