Hello Everyone We've been running our Staging environment on ARM64 based servers (Amazon EC2 T4g) for a while now, and plan to use similar machines to replace our Production environment's x86-64 based servers in the near future. All of our servers are based on Amazon Linux 2 with AdoptOpenJDK 15.0.2 and Tomcat 9. Measured with our application, performance between x86-64 and ARM64 with two similarly sized machines (e.g. T3.large vs T4g.large) is up by an average of 22% on the T4g's. These numbers are largely academic, and will stay that way until we actually deploy a few machines in Production. The ARM64 machines are also cheaper by about 20%, so if all goes well, there aren't real downsides to the move.
I read this correspondence about a year ago: https://marc.info/?l=tomcat-user&w=2&r=1&s=arm64&q=b I'd like to ask the community if anyone has production experience with Tomcat and ARM64/Graviton2, and whether there are specific issues I should beware of. Thanks Chen
