Two tries from Tommy Seymour plus three Ruaridh Jackson penalties and a Scott Wight conversion and penalty helped Warriors cement third place in the RaboDirect PRO12 table.
It was all the perfect response to two disappointing reverses in the Heineken Cup at the hands of Northampton and Ulster as Glasgow claimed a victory at the Stadio di Monigo where PRO12 champions Ospreys had already perished earlier this term.
Toony said: "This was massive. When you look at some of the wins Treviso have had on their patch against the likes of the Ospreys and Scarlets, and the fact that they only lost to Leinster by a single point, it puts just how good this performance was in context.
"There were so many positives and not least the fact the boys showed tremendous character firstly to bounce back from two Heineken Cup defeats but also to come from behind after Treviso had been in front.
"This has now given us a platform into the Dragons game at home in Scotstoun on Friday night and taking a bonus point from the Stadio di Monigo is something that could make all the difference down the line."
Townsend was also keen to salute a number of big individual performances from his stars.
The Warriors head coach said: "I was delighted for Tommy Seymour to come back from his suspension last week to claim two tries and Ryan Wilson was outstanding in the second half with some very big ball carries at key times.
"Scott Wight made a big contribution off the bench as did all our replacements and really it was a team effort."
He went on: "I'm delighted with the spirit the players showed to pursue and claim a win against extremely tough opposition.
"We didn't play as well as we wanted to in the first half and Treviso put us under pressure. But we really stepped up in the second half, and to a man we delivered.
"Niko Matawalu was another who had a great game but the boys were all terrific and we deserved the win in the end."
Looking ahead to Friday's visit of the Dragons, Townsend was keen to highlight the importance of going into the international break on the back of a win.
He said: "This win has given us a great platform into the Dragons game and it is absolutely vital we make the most of it,
"To be going into the international break with back-to-back wins and sitting third would represent a pretty satisfying first quarter and that has to be the target.
"Dragons is a must-win game – that is the bottom line."
