Not necessarily. hslogger could easily accept both, and deal with it
appropriately under the hood. If whatever it prefers under the hood is
supplied to it, I don't see any reason that performance would suffer.
I very much suspect though that you would not likely see a measurable
performance difference either way with hslogger in real-world situations.
