Compressing the linux kernel 3.14.1 sources

Sources are text files, and text files generally have very good compression ratios. Let see how our contenders fare in compressing the linux kernel 3.14.1 source tar file:

While the relative standing remains the same, we can see two differences:

  1. as expected, the compression ratio is somewhat higher
  2. lzop is considerably faster at compression compared to the previous run.

Now, the multi-threaded part:

and scaling:

Compression scaling remain excellent, with pxz in the last place.

Thanks for the post, looks like similar info as ?

I also found this post useful at explaining the differences, the summary seems to be similar in both posts which is good to see people testing these compression get similar results :)
