Description mehrunes 2009-08-13 16:23:49 UTC

tamp is a multi-threaded file compressor built on top of quicklz library, the fastest open-source file compressor i m aware of, produces files slightly larger than lzop, compresses data many times faster than lzop

i set KEYWORDS to *, though i only tested tamp on amd_64 architecture

Comment 3 mehrunes 2009-08-21 03:48:27 UTC

strange that tamp writes 8M when compressing without checking for partial writes. IMHO tamp might fail to write compressed stream when block size is big (though i have not seen it fail yet)

i emailed upstream about this
