Mostly it take only a week or two week to received a decision from ESDC, but I have seen so much of cases in which employers are waiting for 1 month or 2 month for getting decision (Positive LMIA)
Don't need to worry, no body can't judge the time. I have a friend who just received LMIA in just 24 days( date of filing to LMIA received).
One thing you can do is your employer or you can ESDC call center and ask them about your case. You have to get a business number (Associate with CRA ) from the employer because they will ask it from you and they will tell you everything about your case.
