This test is disabled for the following reasons: This test is one of the longer ones in this suite (2979 out of 3559ms total) and nothing is currently monitoring the performance, if this test were to be 20% slower one day, no-one would actually notice. there are no asserts, the test actually cannot fail. it's good to have some benchmark code, so like some of the other mesh benchmark code, exclude it using an `#ifdef` guard so i can be easily re-enabled when needed. reviewed by: jbakker Differential Revision: https://developer.blender.org/D16314
