Con Kolivas 70e7866271 Include arpa/inet.h for those OSs that have endian details elsewhere. 2011-03-22 21:47:24 +11:00
ckolivas f56e48c4f2 Modify maxram to mean the most we'll allocate in one chunk and add usable_ram for the most we'll allocate to one task. 
Limit all maxram on 32bits to 1GB since most don't like mallocing more than this.
Update testing to allow larger total amount based on usable ram while sticking to maxram limit per alloc.

Con Kolivas 8bf60c3114 Don't round to page size if the entire buffer will fit, otherwise this generates one extra pass of a tiny chunk. 2011-02-24 11:38:31 +11:00
Con Kolivas 9c8b1ee795 Deprecate the -M option as it is no longer of any significant utility compared to the -U option. 2011-02-22 20:38:39 +11:00
Con Kolivas bb33f7571c Multi-threading speed ups. 
Add one more thread on compression and decompression to account for the staggered nature of thread recruitment.
Make the initial buffer slightly smaller and make it progressively larger, thus recruiting threads sooner and more evenly.
This also speeds up decompression for the same reason.
Check the amount of memory being used by each thread on decompression to ensure we don't try to recruit too much ram.
