In response to r3454: It's great you have a plan to solve the performance problem but I won't approve this till we've seen that future branch proposed and passing the affected test a few times.
If we land this and don't re-enable the test, there's a chance the performance regression (which itself is more important than this branch) might not get resolved. So I would like to see a working solution to the performance regression on the horizon before we even temporarily disable the test for it.
