Hey guys,
It works, Amount of time required for compression is low. [ using Plzip ]
But that will reduce compression ratio.
If I try to achieve the same compression ratio of Lzip with Plzip then,
The required amount of time is not so different.
So I guess one will have to either use a very powerful processor or
will have to choose between compression ratio or time.
Am I right?

You can obtain both high compression ratio and fast compression speed, but only on large enough files. The home page of plzip gives a hint:

http://www.nongnu.org/lzip/plzip.html
"Note that the number of usable threads is limited by file size; on files larger than a few GB plzip can use hundreds of processors, but on files of only a few MB plzip is no faster than lzip."

And the manual page explains the details:
http://www.nongnu.org/lzip/manual/plzip_manual.html#Minimum-file-sizes


Best regards,
Antonio.
