Description
The summary profile in the plan right now doesn't differentiate between the build and probe sides of the join when computing the min and max time taken. This is misleading because in many cases the build will take far less time, and therefore there will be a wide range between min and max time even if all probes and builds take roughly the same amount of time respectively. This leads to a false appearance of some sort of skew or other performance problem when the behavior is normal and expected.
