ArcMap is lagging when I click the measure tool, my data isn't particularly big (biggest .shp is ~150mb) and my PC is brand new. Any idea what may be causing this?

After you activate the Measure Tool, press the Space Bar to disable snapping. There should be no lag.

    This is a handy trick, but to clarify: you need to hold the space bar down while using the Measure tool to temporarily disable snapping. Simply pressing it once will only disable it for a fraction of a second.

    Alternatively, open the Snapping Tool bar and turn snapping off.
