Marked as flaky in http://trac.webkit.org/projects/webkit/changeset/208850
Comment 2 Brady Eidson 2016-11-17 13:45:15 PST
It is only on the verge of timing out in debug builds - Plenty fast in release builds.
Comment 3 Brady Eidson 2016-11-17 13:45:41 PST
(And I see you only marked it flaky for Debug! Great!)
Comment 4 Brady Eidson 2016-12-02 09:35:25 PST
This timing out is not a real correctness bug, but rather a real performance bug.

We need to speed up cursors in general, specifically for debug builds of course.

We'll need to have cursors prefetch the next record or two.
Comment 5 Joseph Pecoraro 2018-08-09 17:07:35 PDT
Closing. El Capitan expectations have been removed.
