gzip runs faster without assembly
Last modified: 2007-03-26 23:37:02 EDT
Compression speed can be improved up to 27% by disabling the assembly
version of the match_longest function. It appears that gcc does a better
job in optimizing the C version of that function. Just disable the ASMV
define. Decompression speed is not affected. Maintainers of the gzip
package have been notified.
Weird - will investigate.
Verified and turned off (with DEFS=-DNO_ASM).
1.3-7 will eventually show up in Rawhide.
so no "massive performance enhancement" official update in sight? :->
Nah, it works correctly as shipped. Besides, most systems don't spend that much
time doing it. Now, if it was glibc....
