Assembly optimization?

Question

Programming

Good time of the day.
I understand with the assembler and I can not understand one procedure.
.parse_char:
lodsb
test al, al
jz .config_end
cmp al, 10
je .run_command
cmp al, 13
je .run_command
jmp .parse_char
As far as I understand, test is needed here for optimization. The full code of the project I'm trying to understand: https://yadi.sk/d/MW3fNS7xgtEKr

Answer 1

test al,al is equivalent to comparing register al with 0. but yes, this is some optimization compared to cmp al, 0
