I've been through MAN (T1 for T3) and LPL in the last couple of months, both first wave departures. Security took about 35 mins at MAN and about 30 mins at LPL.
The issues at MAN have been well publicised, but the idea that that is the case at all times is as incorrect as the idea that you can get through at LPL in <10 minutes all the time.
Didnt say it was, i have already replied to the passengers here some time ago. I have been through LPL twice this month, one time security was 10 mins the time before about 15 mins. Depends on time of day.
