Multi core compressors

[bs0409]

Is there any compression software which makes maximum use of multiple cores on a system and also gives good compression ratio??

tried Winrar but it has low compression ratio.....

Try 7z with PMD (don't remember the exact name) compression. Its awesome, ohh and it only works in windows.

I think you need KGB Archiver ! very different in its approach and very high compression ratios. although it makes files which can only be deflated by it only.

Does it make use of more than one core for compression....

I have very large files and a quad core processor. So unless the compression program makes use of all the 4 cores, It will take a very long time for me.

Tried KGB archiver but it is very slow and does not make use of more than 1 core........

pbzip2 gives good results and scales nearly linearly. 7za supports atleast two cores at the moment by default, I'm not sure if it uses all cores on quad-core machines. If so, use lzma -2, which will give better compression than bzip2 and which should be faster also.
