Bug 1715759 - Add a pref to control allocation site based pretrening r?jandem
48 bytes, text/x-phabricator-request
Details | Review

The pretenuring work landed enabled by deafult but there's concern it's causing some performance regressions. We should add a pref so we can enable/disable this easily.

This doesn't change the state of this feature which currently enabled, but will
allow us to disable it easily if necessary.
