thanks for the quick reply and sorry if the subject was already mentioned before.
its funny though, i tried to find a relative thread but didn't find any, yet there was a recent one that touch the same exact subject xD
i checked the referred link out and found that the fastest way is by proftpd but its old and unstable also its need older frimware so i need to downgrade to a more buggy frameware (not that the current one is way better xD) so i would stick with the tinySmb for now but if the tinysmb is using ftp then it should use the whole speed with no encryption right ?
