- By executing the aggregation on the server-side a performance improvement up to a factor 100 100x can be seen if one is using the hash table for the iteration. If one is directly traversing the Log, a performance improvement of up to a factor 450x can be seen (although it is questionable if a Log traversal would be appropriate for executing server-side data operations).
- When traversing a set of distinct objects, retrieving a single object takes about 7-8?s (or a RAMCloud client can request about 130.000 objects/sec from a single RAMCloud server).
- When invoking the hashTable forEach method the whole allocated memory for the hashtable has to be traversed. This is fine if the hashtable is densely packed with objects. In case of a sparse population with objects this introduces a penalty.
