Summary[edit]

Description
English: This is a comparison of popular compression formats by how many nanoseconds it takes to compress each format. The horizontal scale shows tens of kilobytes.

To recreate run this on a Linux computer:

for testnum in $(seq 0 256); do
    testnum=$(expr $testnum '*' 10)
    for archiver in bzip2 lzma xz gzip lzip lzop lrzip; do
        dd if=/dev/zero of=$testnum.zero bs="$testnum"'k' count=1
        $archiver $testnum.zero
        rm $testnum.zero
        c=$(date +%s%N)
        $archiver -d $testnum.zero.*
        d=$(date +%s%N)
        total=$(echo $d-$c | bc)
        echo $total >> $archiver
        rm $testnum.zero *.bz2 *.lzma *.gz *.xz *.lzo *.lz *.lrz
    done
