If during schema evolution a conversion streamer info is required, we have to load the schema info records from the ROOT file. If the RNTuple is loaded through the RMiniFile, this requires an extra call.

Is this an optimization to only load the streamer infos when needed? How much would it cost to always load them when opening the file?
