Benchmark (De)Serialization using Scalameter - scala

Question

So I have been struggling to understand how to use Scalameter for my use case. I have two methods: toJson (serialization) and fromJson(deserialization) which belong to a scala object class (static).
What I want to achieve is benchmarking the runtime for these two methods against a variety of different datasets e.g. stateSmall, stateMedium, etc.
Tried something very basic, but I have a feeling this isn't the correct way to define these benchmarks; Since it only run once - preferably I would want this to run 1000+ times to get the average runtime.
In the documentation, the examples I've seen are not super clear for me on how to achieve this.
object StateSerializerBenchmark extends Bench.LocalTime {
val stateSerializer = Gen.single("owner")(StateSerializer)
performance of "StateSerializer" in {
measure method "toJson - small" in {
using(stateSerializer) in {
_.toJson(BenchmarkFixtures.userProfileStateSmall)
}
}
measure method "toJson - medium" in {
using(stateSerializer) in {
_.toJson(BenchmarkFixtures.userProfileMedium)
}
}
}
}
Update
An alternative way which seems a bit better
object StateSerializerBenchmark extends Bench.LocalTime {
val sizes = Gen.range("sizes")(1, 100, 10)
val userProfileStateSRange = for {
size <- sizes
} yield List.fill(size)(BenchmarkFixtures.userProfileStateMedium)
val userProfileStateMRange = for {
size <- sizes
} yield List.fill(size)(BenchmarkFixtures.userProfileStateLarge)
performance of "StateSerializer" in {
measure method "toJson - small" in {
using(userProfileStateSRange) in {
s => StateSerializer.toJson(s)
}
}
measure method "toJson - medium" in {
using(userProfileStateMRange) in {
s => StateSerializer.toJson(s)
}
}
measure method "toJson - large" in {
using(userProfileStateMRange) in {
s => StateSerializer.toJson(s)
}
}
}
}
Any examples or pointers would be appreciated.
