Looks like there are many possible scenario on how your Bitcoin was stolen and there's no way to find out which scenario actually happened, so i strongly suggest you to secure all your devices and server (if you haven't done it yet).

It would depend on what machine the hacker use and the entropy of your password. You can try some tools to predict how long it would take to crack your password such as https://tmedweb.tulane.edu/content_open/bfcalc.php.

36.99 minutes in  the case of offline  attack scenario and 2.22 sec if the massive cracking array of relevant devices is used, according to https://www.grc.com/haystack.htm   To be on the safe side the entropy of password should be at least 256 bit and password itself should consist of two parts, i.e dynamic and static, the latter delivered via HW security key (https://bitcointalk.org/index.php?topic=5223442.msg53778608#msg53778608).

Those are rough estimation and actual time to brute-force the password depends on algorithm used for encryption (encryption require more computational power compared with hashing) and hardware owned by the hacker.
