Maarten, Daniel,

Do we have any ww-mutex performance tests somewhere that can be used to test the impact of implementation details on various locking scenarios?

Thanks,

The thing that comes to my mind are some of the kms_cursor_legacy tests that have been proven to be sensitive to locking issues before. All subtests with (pipe-*/all-pipes)-(single/forked/torture)-(bo/move) try to do cursor updates as fast as possible, and report how many updates have been done.

Thanks, Maarten.
