Subtopic: performance measurement 
| Quote: portable API for performance tools using the on-chip performance monitoring hardware; measurements per-thread; PAPI [»muccP6_2005]
|
Subtopic: object management
| Quote: quidelines for faster Java; reduce frequency of object allocation and object copies; up to 15x improvement [»klemR6_1999]
| | Quote: many optimizations depend on copies creating equal values while not affecting other values; if not enforced, user types can not be optimized [»dehnJC4_1998]
|
Subtopic: object inlining
| Quote: object inlining allocates single-reference child objects within their container class; averages 10% faster; expensive to compute [»dolbJ10_1998]
| | Quote: automatically inline single-reference objects; 25% fewer cache misses; 14% faster programs [»dolbJ6_2000]
|
Subtopic: inline function
| Quote: use inline functions to make interface classes affordable; e.g., an inline forwarding function that adjusts the type without generating additional code [»stroB_1991]
|
Subtopic: optimizing dispatch tables
| Quote: use compressed dispatch tables for dynamic, multimethod dispatch in constant time [»dujaE1_1998]
| | Quote: replace virtual function tables with static type testing code; allows inlined function calls [»zendO10_1997]
| | Quote: use a hashed, interface method table for efficient interface dispatch; comparable to a virtual method call [»alpeB10_2001]
| | Quote: dynamic method calls with direct devirtualizing and code patching; inline code is executed until assumptions fail and backup code takes its place; mean of 16% faster [»ishiK10_2000]
| | Quote: CLR objects include vtable pointers for method dispatch and simple type handles [»kennA6_2001]
| | Quote: use interval containment and type slicing for space efficient dispatch tables with multiple inheritance; 2.6x less space than the row displacement algorithm [»zibiY11_2002]
| | Quote: efficient interface dispatch (invokevirtual) using fixed-sized, interface method tables, disambiguated by a interface method signature; used by Jalapeno [»alpeB6_2001]
|
Subtopic: type tests
| Quote: incremental algorithm for constant-time subtyping tests for multiple inheritance
|
Subtopic: binary operators
| Quote: implement binary operators of complicated types with assignment operators; e.g., implement matrix addition in terms of '+=' [»stroB_1991]
| Quote: designed Java's semantics so that 'a=b+c' and 'p.m' could be implemented quickly; e.g., lead to static typing
