Comment (by Joachim Breitner <mail@?>):

 In [changeset:7d29fbf373befbc0ee60dff01f6a9cabee047862/testsuite]:
 {{{
 #!CommitTicketReference repository="testsuite"
 revision="7d29fbf373befbc0ee60dff01f6a9cabee047862"
 Flag to test suite: SKIP_PERF_TESTS

 More often than not the output of the performance tests is in the way,
 rather than helping. This allows the use of `make SKIP_PERF_TESTS=YES`
 to skip these tests. Fixes #8413
