python-pgzip 0.4.0-2
Package Information
| Description | multithreaded gzip implementation for Python pgzip is a multi-threaded gzip implementation for python that increases the compression and decompression performance. Compression and decompression performance gains are made by parallelizing the usage of block indexing within a gzip file. Block indexing utilizes gzip's FEXTRA feature which records the index of compressed members. FEXTRA is defined in the official gzip specification starting at version 4.3. Because FEXTRA is part of the gzip specification, pgzip is compatible with regular gzip files. pgzip is ~25X faster for compression and ~7X faster for decompression when benchmarked on a 24 core machine. Performance is limited only by I/O and the python interpreter. Theoretically, the compression and decompression speed should be linear with the number of cores available. However, I/O and a language's general performance limits the compression and decompression speed in practice. |
