The version available on apt is older. The performance numbers are from master. I am on a device with SSD now and `nnn` master consistently gives a better performance in 3 runs. Here are the numbers I see with $LS_COLORS set to: ex=00:su=00:sg=00:ca=00: nnn (still shows dir colors as it's designed to): 0.00user 0.00system 0:00.01elapsed 33%CPU (0avgtext+0avgdata 3420maxresident)k 0inputs+0outputs (0major+319minor)pagefaults 0swaps ls (no colors): 0.00user 0.01system 0:00.02elapsed 60%CPU (0avgtext+0avgdata 3724maxresident)k 0inputs+0outputs (0major+297minor)pagefaults 0swaps And going deeper, with the same $LS_COLORS, see the difference in the number of calls (no wonder `nnn` outperforms `ls`): $ time strace -c /usr/local/bin/nnn /usr/bin | wc -l % time seconds usecs/call calls errors syscall ------ ----------- ----------- --------- --------- ---------------- 82.55 0.004592 2 1988 newfstatat 8.47 0.000471 118 4 getdents 2.82 0.000157 3 58 1 stat 1.89 0.000105 105 1 inotify_add_watch 1.64 0.000091 9 10 brk 1.33 0.000074 5 15 close 0.23 0.000013 1 14 openat 0.18 0.000010 3 4 write 0.18 0.000010 0 22 2 ioctl 0.13 0.000007 0 15 fstat 0.13 0.000007 1 14 mmap 0.13 0.000007 7 1 inotify_rm_watch 0.11 0.000006 1 8 read 0.11 0.000006 6 1 1 unlink 0.07 0.000004 4 1 sysinfo 0.05 0.000003 3 1 lseek 0.00 0.000000 0 2 lstat 0.00 0.000000 0 10 mprotect 0.00 0.000000 0 1 munmap 0.00 0.000000 0 9 rt_sigaction 0.00 0.000000 0 9 7 access 0.00 0.000000 0 1 execve 0.00 0.000000 0 1 arch_prctl 0.00 0.000000 0 1 inotify_init1 ------ ----------- ----------- --------- --------- ---------------- 100.00 0.005563 2191 11 total 0.03user 0.01system 0:00.06elapsed 74%CPU (0avgtext+0avgdata 3424maxresident)k 2968inputs+0outputs (7major+541minor)pagefaults 0swaps 0 $ time strace -c ls -l /usr/bin | wc -l % time seconds usecs/call calls errors syscall ------ ----------- ----------- --------- --------- ---------------- 32.03 0.004882 2 1989 lstat 30.42 0.004636 2 1989 1989 lgetxattr 22.45 0.003421 2 1548 1548 getxattr 6.57 0.001002 2 442 readlink 6.15 0.000938 235 4 getdents 0.45 0.000068 2 33 5 openat 0.43 0.000066 6 11 munmap 0.31 0.000047 1 34 close 0.30 0.000045 1 40 mmap 0.26 0.000040 2 17 lseek 0.20 0.000031 1 30 fstat 0.10 0.000015 4 4 4 connect 0.09 0.000014 3 5 brk 0.07 0.000011 3 4 socket 0.07 0.000010 0 31 write 0.06 0.000009 9 1 mremap 0.03 0.000005 0 17 read 0.00 0.000000 0 20 mprotect 0.00 0.000000 0 2 rt_sigaction 0.00 0.000000 0 1 rt_sigprocmask 0.00 0.000000 0 2 2 ioctl 0.00 0.000000 0 12 12 access 0.00 0.000000 0 1 execve 0.00 0.000000 0 2 2 statfs 0.00 0.000000 0 1 arch_prctl 0.00 0.000000 0 1 futex 0.00 0.000000 0 1 set_tid_address 0.00 0.000000 0 1 set_robust_list 0.00 0.000000 0 1 prlimit64 ------ ----------- ----------- --------- --------- ---------------- 100.00 0.015240 6244 3562 total 0.04user 0.06system 0:00.09elapsed 114%CPU (0avgtext+0avgdata 3676maxresident)k 0inputs+0outputs (0major+521minor)pagefaults 0swaps 1989
