I flew in economy from T3 yesterday, it took me 1hr30 mins to clear security check after check-in process. Security check is upstairs, so you need to take escalator for that. Before the escalator there was long queue, it took me almost 40 minutes reach there. After going up there were two lines for regular and fast track security. After reaching upstairs I have seen fast security line was moving really fast. They gave us small plastic bag , you need put all liquid bottle in that like perfume, soap, shampoo, paste, shaving gel, toothpaste etc. I have seen lot people throwing items in trash and dumping stuff like water, milk etc before the security. My flight was at 2pm I have checked in online, dropped bag (it took me 5mins) standing in line at 9:30am for security finished security around 11am. Hope things get better in future.
