Phacility instances come up pretty fast right now, but they could be faster. One easy thing we could do is skip database verification on initialization, since we know we're initializing into a good state and verification is somewhat slow.
A more involved thing we could do is pre-allocate databases, although this seems very complicated and probably not worth it. Providing a UI (T5166) is probably a better improvement here than adding a lot of complexity to save a couple of seconds.
