@mtaylor @michaelandrepearce Yep and it isn't changing the way the mapped
journal works: it uses a different code path from the journal, without changing
the MappedSequentialFile in any of its parts.
I agree that I could provide relative measurements to show which impact it
has vs the original version: with @orpiske probably we could start providing
some relative numbers before merging anything. @orpiske wdyt?
