So far we didn't face any issue related to ARM64 & Tomcat in our application! I've introduced the testing on TravisCI that you have found. In addition for my daily job we have created a nightly test setup: - build and test Tomcat 9.x (as at Travis) - run some smoke tests with our application - run some performance tests on x86_64 and ARM64 VMs with similar hardware specs. The results for both architectures are very similar. One thing that still bothers me is that the throughput on HTTPS is 3 times less than HTTP. It must be something in our setup, I believe. The SSL handshake should happen once per connection and then the connection should be reused with keep-alive. Once I feel more certain what is happening I will probably write a blog to share our experience.
