PyCon 2005 1Improving Python’s Memory AllocatorEvan Jones http://evanjones.ca/Abstract Python automatically manages memory using reference counting. In order to providegood performance for typical programs, Python provides its own memory allocator forsmall objects ( 256 bytes). However, the original implementation does not releasememory to the operating system, which can cause performance problems. This paperdescribes how the original implementation works, and how the prob
