How many hours was the traffic after a concert in the PH Stadium / Arena?

Hi previous concert-goers, how many hours was the traffic after a concert in the PH Stadium / Arena? How long did it take for you to get home or return to your accommodations?

I'm planning to attend a concert on a weekend and returning right after con due to classes the next day. Just wanna know how many hours was the traffic so I know what to expect, especially those outside Manila or Bulacan. Thank you!
