Compares time of cloning a Git repository vs. compressing & extracting it. GIT_REPOSITORY_URL needs to be set.

printf 'Tar compress time: %s seconds\n' "${compressTime}"
printf 'Tar extract time: %s seconds\n' "${extractTime}"
printf 'Tar compress + extract time: %s seconds\n' "$((compressTime+extractTime))"

rm -rf ./git-repo
rm -rf ./extracted-tar
