Nuances of Android Runtime vs HotSpot VM

While investigating the performance of sequence and Java stream on the standard HotSpot VM, we got some interesting results that are very different from the results of Android Runtime. To understand and explain the reason for such differences, we will have to dive into the depths of compilation logs and nuances of the Android virtual machine and the standard HotSpot VM.

We will examine the performance of not only lazy transformations but also functional types in Kotlin and share far-reaching conclusions.
