Is there are reason to prefer one or the other of `Json.decodeFromString(file.readText())` vs. `file.outputStream().use { Json.decodeFromStream(it) }`?

given what kotlinx.serialization has been optimized for, I would expect the first to perform better. you can do your own benchmarking

Ah, interesting, thanks for that pointer!

However, from skimming over the issue it seems to have been addressed with version 1.5.0, so there is no performance difference anymore?

run your own benchmarks. I'm pretty sure it's still slower than Moshi whose bytes-to-UTF-8 path has been much more used and optimized

I'm not really interested in a comparison to Moshi, but in a KxS string vs stream API comparison. Do you have any pointers to benchmarks for that?

If you do write your own microbenchmark though, I highly recommend posting it here, because it's notoriously easy to write them wrong, so you'll want it to be reviewed by other people

Thanks, but I'll most probably not go into the rabbit hole of writing my own benchmark :wink: I was more looking for a "serious" source to refer to.
