Hello Antonio! I didn't try to know exact time of extraction but I got strange results when I tried to get exact time of listing the archive. The followinfg results for standart tar: $ time tar -t -f ./tde-i18n-20220504_e67bfc8629.tar.lz real 0m27.391s user 0m26.549s sys 0m1.102s The followinfg results for tarlz without -f option: $ time tarlz -t ./tde-i18n-20220504_e67bfc8629.tar.lz real 56m5.702s user 0m0.001s sys 0m0.006s I couldn't stand my patience so I interrupted process with CTRL+C But the prevoius command with "-f" flag: $ time tarlz -t ./tde-i18n-20220504_e67bfc8629.tar.lz real 0m11.626s user 0m34.261s sys 0m0.510s
