The Warriors scored eight tries to move up to fourth in Conference A, but are already 14 points behind leaders Leinster.
While pleased with many aspects of his side's performance Dave Rennie says there's still work to do with the opening weekend of the European campaign just around the corner.
"I was really happy first half. We were reasonably accurate and we turned pressure into points but we're a bit frustrated with the second-half," said Rennie.
"We just felt that the game stuttered through. I thought we defended well - we turned a lot of ball over and we profited off a couple but we gave a couple back as well.
"We need to be a bit more accurate but it's a step in the right direction."
"I was really happy with all of the international boys that came back in," Rennie added. "George is a livewire and he's demanding that boys get beyond the ball to generate some quick pill, and when we did that, we put them under a lot of pressure.
"I thought Adam (Hastings) controlled the game well and put us in the right parts of the park too.
"Zander is going to have a massive career," the Head Coach continued. "As a tighthead prop, he's a really good scrummager but he's a hell of a good player around the park, in carry, tackle and clean. He's got a bit of a dark side and that's important."
Rennie admitted Glasgow's improved performance stands them in good stead as they prepare for a trip to Zebre next Saturday before they welcome Sale to Scotstoun the following week in the first round of the Heineken Cup.
"We needed that," the Head Coach said. "It's not that we're lacking in confidence because we've been preparing really well but it's good to get a quality performance on the park. Hopefully we can build on tonight.
"They've recruited a fair bit of South African beef, and they'll want to get us into a bit of an arm wrestle so our ability to create quick ball and play at a tempo that will stress them will be important."
