Good to hear - these numbers look promising. The apparent slowdown on LiveDebugValues is unfortunate and might be worth fixing if possible, but it's nothing close to the "old" performance. The question now is whether the presence of DBG_VALUE_LISTs causes a large performance hit; I don't think there's anything in there that should cause any dire issues, but I appreciate any certainty that can be given.
