i downloaded and compiled p7zip_16.02_src_all.tar.bz2 from here
compile was done on my raspberry pi 3B running buster(debian 10)
i want to compress a large file in a NAS mounted on /mnt in my raspberry pi running buster
gzip 1.9 does this in 4 hours
7za takes 10+ hours to compre ss the same file
this is the file (dd output)
-rwxr-xr-x 1 root root 61530439680 Sep 20 02:17 backup_20200920_003002.img
what gives. what can i do to make 7z beat the gzip time?
try 7z or xz format in 7-Zip and -mx1 or -mx3 switch
