problem was HTTPS traffic got slow even with good bandwidth .

Networks that were using an incorrect tracking method resulted in security features failing to identify clients correctly on the newer firmware levels.
Depending on if you use any layer 3 devices downstream of the MX, we recommend different tracking methods as outlined in the documentation Here.
