Subject: gzip: Decompression performance improvement
Package: gzip
Version: 1.3.12-2ubuntu1
Severity: wishlist
*** Please type your report below this line ***
I think Jean-loup Gailly's emphasis with gzip is for portability. As
such,
Mark Adler's performance changes in zlib-1.2.0 haven't been ported
across.
>From the zlib-1.2.3 ChangeLog
Changes in 1.2.0 (9 March 2003)
- New and improved inflate code
- About 20% faster
- Does not allocate 32K window unless and until needed
...
- New and improved crc32()
- About 50% faster
OpenBSD 4.2 compress uses zlib, testing with the 120Mb openbsd source
archive
a quick & dirty compress port on Ubuntu 7.10 x86_64 gave ~25%
decompression
speed improvement. Assuming that the compress tests as compatible with
debian
ncompress, please consider using this as the gzip decompressor for
gunzip zcat et al, which may require patching other utilities to use
that
rather than gzip -d.
See patches at end.
