Try also timing the second and third runs on a single build tree<br>
to get timings without all the platform introspection tests.<br>
<br>
You could clone the CMake Git repository, build from source with<br>
-DCMAKE_BUILD_TYPE=RelWithDebInfo and then run it through a<br>
profiler (e.g. valgrind --tool=callgrind). Alternatively you<br>
could `git bisect` between v3.4.3 and v3.5.0-rc1 to see if there<br>
is a small range of commits that causes the regression. That<br>
could really help narrow it down.<br>
<br>
