    7 In terms of the approach: We'll enable TCL profiling, and generate results for each of the three operations (reclaim, rev-upgrade, clean), across both v2.6.4 and v2.7.1. To ensure we're comparing apples-to-apples, that will be done via a cloned VM, with an identical set of installed ports. The operations will also be run twice, with the first run done to prime the filesystem cache. The 2nd run will include profiling enabled.
