Hi guys
The Perforce Tag Files action doesn't have the 'Do not capture output' option that the Perforce LabelSync action has. It does indeed make quite a speed difference.
You can create the label, and then labelsync to effect a tag with two actions to get the speed up, but doing it in one Tag action with the speed up would be a nice improvement since Tag seems to exist to for one step convenience.
