How to Utilize Java Benchmarks With Arm Processors

I have seen a lot of speculation surrounding ARM processors, specifically after Apple announced its plan to change over to Arm-based processors. Many people assume that the performance will be similar to a Raspberry Pi, however, this is incorrect. While Java on ARM is not uncommon, there has been a recent spike due to increased ARM investments from cloUd vendors. Amazon and Microsoft have taken steps towards this, with Amazon updating its ARM offerings, and Microsoft porting the JVM to Arm64 for Windows, which will be helpful for future Azure support.

In this article, I will show the Java benchmarks I took on different AWS EC2 instances, and for fun on my laptop.

  1. Amazon a1.large (ARMv8 Cortex-A72, 2 Cores, 4GB RAM).
  2. Amazon m6g.medium (ARMv8 Neoverse-N1, 1 Core, 4GB RAM).
  3. Amazon t3.medium (Intel Xeon Platinum 8259CL, 1 Core / 2 Threads, 4GB RAM).
  4. Apple MacBook Pro (Intel i9 2.4GHz, 8 Core / 16 Threads, 64GB RAM).

The Arm trademark will be referred to as such. Although it was previously written “ARM”, it is now “Arm”.
