Please discuss the specific goals and possible approaches to these problems!
CPython
- Implement PEPs for optimizing global and attribute lookups
- Implement faster floating point ops
- Implement portions of decimal module in C
- Struct module improvements (e.g. struct.compile, struct.finditer)
- Create a string variant that provides lazy slicing without copying
- Allow selective removal of unused features (e.g. profiling support)
- Faster parsing of strings and bytes into int, long, etc.
- Buffer for use with network i/o
- More collections
- ordered dictionary
- alternate list optimized for fast insertion and deletion
- red/black tree
- pivot tables
- skip list
Create a 64 bit PyInt type (for 32 bit machines)
- Optimize str object methods
- Add itertools.imerge() and itertools.izip_longest()
Pure Python Projects
- Improve language shootout submissions
- Improve the API for timeit.py
Update PythonPerformanceTips
Twisted
- Speed improvements to select and poll reactors
- Reactor based on /dev/epoll
- Better integration with psyco
- Improvements against twisted benchmark
Psyco
- Support for generator expressions
- Support for nested scopes
- Support for more dictionary operations
- Speedup float arithmetic
- Support for more built-ins (e.g. int(), long(), float(), etc.)
- Upgrade for python 2.5
- Better tools for profiling psyco-ness of application
- Investigate usefulness of IVM (with aim to producing a more streamlined dispatch loop)
- LLVM backend
- Virtualised longs (for long longs)
Virtualised slots (Ability to cache getattribute() values)
PyPy
- JIT compiler
- LLVM backend
- RPython extension modules for CPython
