Details

A profile of tresize from the talos machines would suggest that an excessive amount of time is being sent in calls to glXSwapIntervalEXT; roughly 13% of the compositor thread's cycles. The stack suggests that this is due to synchronous X calls being made to the nvidia DDX driver.

We should aim to cache the swap interval for the drawable locally, or set it once during drawable creation.
