Dynamic
Optimizers also do better memory
|
|
|
optimization
|
|
|
|
– |
Two stage memory
allocation allows very efficient
|
|
|
allocation of
short-lived objects
|
|
|
|
l |
Objects are
initially allocated in a “nursery”
|
|
|
|
– |
Allocated in
contiguous stack-like fashion – very fast
|
|
|
|
– |
Most objects in
the nursery have been discarded before the
|
|
|
nursery becomes
full
|
|
|
|
l |
Only long lived
objects need to be moved to long-term
|
|
|
storage
|
|
|
|
– |
Java objects can
be moved in memory (unlike C++)
|
|
|
l |
Objects with
many cross-references can be moved closer
|
|
|
together
|
|
|
|
l |
Memory
fragmentation can be eliminated
