Yep, we haven't measured yet how slower it gets but we don't have a lot of traffic for this logger.
It was annoying to have a delay when observing logs so we flush the stream all the time. We were also afraid of missing information in the case of a pharo crash (hopefully that doesnt happen too much ;))
