Yes I just checked it after installing strace

strace -c ls gave me this

100.00 0.002709 13 198 5 total

strace -c eza gave me this

100.00 0.006125 12 476 48 total

strace -c lsr gave me this

100.00 0.001277 33 38 total

So seeing the number of syscalls in the calls directory

198 : ls

476 : eza

33 : lsr

A meaningful difference indeed!
