The Swans kicked eight goals to one to half-time and then really put their foot down, slamming through 14 more goals the rest of the way in a breathtaking 110-point triumph.
If there was one black mark, and there really wasn't, it was some wasteful shots on goal in the second term, when the home side kicked 4.5 along with two efforts out on the full.
Five talking points: Sydney Swans v Geelong
But it would be the hardest of taskmasters to criticise that from a 22.16 (148) to 5.8 (38) destruction of the Cats, Longmire not being one of them.
"We had a few opportunities, particularly in that second quarter," he said.
"You're always aiming for utopia I guess as far as finishing the work off.
"But the work in general was pretty strong. We've been playing some good footy over the last five weeks and wanted to come into the game and keep that momentum going.
"We had 10 more tackles than the opposition (68-58), even though we had a lot of the ball (winning the disposals 466-359).
"That continues to be the foundation of what we need to do, putting pressure on the opposition, and it was a really good performance."
During his post-match press conference, Longmire was asked about a number of his players, including Kurt Tippett (five goals), Lance Franklin (23 touches, four goals), Adam Goodes (three goals) and Craig Bird (33 possessions).
Naturally, big-name recruits Tippett and Franklin were particularly prominent, having now kicked a total of 23 goals in their three appearances together thus far.
But when asked about the best part of the performance, Longmire was keen to highlight the efforts of all his players across the board.
"Probably the weight of numbers across the entire 22 and the consistency over the four quarters," he said.
"It's very difficult in AFL football to get all players playing well and playing well over four quarters for as long as we did tonight.
"We've got enormous respect for the Geelong footy club, they've been able to do it for 10 years.
"They've been incredible with what they've been able to do and so we need to make sure we continue to try to put the pressure on like they've been able to do for such a long time."
The Swans’ 1-3 start to the season now seems a distant memory, with their record now standing at 7-3 with a big percentage boost on Thursday night.
But in typical style, Longmire wasn't getting carried away.
"(It's) round 10 (11),” he said. "We play Gold Coast next week, who are in the top four.
"We just have to keep working and that's what we'll do. We've got to a stage where we're able to win games of footy because we work hard and we don't want to stray from that.
"As soon as we stray from that, we come back to the field, and we don't want to do that."
Yet the overriding sense after this game was that the field is now chasing them.
