Details

Summary

Ref T13242. Currently, the transaction query loads handles by default (this is unusual). We don't need them, so turn them off.

Test Plan

No apparent behavioral change, will compare production profiles.

Event Timeline

(My case for this and D20067 is a little weak since XHProf isn't running locally until I sort out T13232 by compiling Gentoo nine times, but I think they're almost certainly actual performance improvements and I just wanted to spend a few minutes on it and get rid of anything flagrantly silly.)
