Firstly, I wanna which one's more faster and better, ZCMD or YCMD for command processing.

[Basicz]

YCMD is more faster.
YCMD got more functions.
I prefer YCMD.

[Lorenc_]

YCMD is better though ZCMD is great for easy storage and command creating.. Its one of the fastest command processer's as well. I would prefer ZCMD since I haven't tried YCMD

Overall, go check the threads, they have your information

Second speed question: Which is the fastest and efficient with better functions folder management include, yini or dFile? Or is there any better one then that?

[FireCat]

YINI or SII.

Are they faster than the default system of pawn? I heard somewhere not..

[cessil]

if you check the ycmd thread, then you'd see ycmd is faster according to ******' tests.
as far as ini systems go all of them use pawn functions anyway but they make it easier to use, last time i checked cini was the fastest because you can write or read multiple variables using the one function
