Sizing The Heap
● Heap size influences the following
– GC frequency and collection times
– Number of short and long term objects
– Fragmentation and locality problems
● Undersized heap with concurrent collector
– leads to Full GCs with increase in load
– Fragmentation problems
● Oversized heap
– leads to increased collection times
– locality problems (smear problem)
– Use ISM and variable page sizes to reduce smear problem
● Size heap to handle peak and burst loads |
