Hola Tomcat community!
We consider using AWS Graviton [1] based instances which use ARM64
processors for our backend services.
I've googled around and found [2] saying that Tomcat is being tested on
ARM64 architecture at TravisCI! This is great!
Does this mean that Tomcat is officially supported on ARM64 ? I was not
able to find any specific documentation listing which platforms are
officially supported.
Does anyone from the community have any experience with Tomcat/HTTPD on
ARM64 in production ?
I work a lot with ARM64 servers lately!
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.
OpenSSL or SunJSSE?
Both.
With OpenSSL it is slightly faster than with JSSE, but again around 3 times
slower than HTTP.
Here are some details:
Tomcat: 9.x nightly build
tcnative: nightly build from master branch
JDK: AdoptJDK 14
OpenSSL 1.1.1 11 Sep 2018 (this comes from Ubuntu 18.04 repos. I will try
with a newer build)
JMeter: 5.2.1
The application is Spring Boot 2.2.6 with REST GET/PUT/POST/DELETE
endpoints that simply sets/gets data to/from Memcached. No usage of Spring
Security! No redirects from HTTP to HTTPS!
Let me know if you need more information!
Coming back to this almost a year later. :)
My guess about the TLS performance is that your x86 chips have built-in
hardware support for crypto primitives used by the cipher suite(s) you
are testing, and your ARM64 chips do not.
Either that, or neither OpenSSL nor Java are able to use those ARM64
hardware features because they are not aware of them (yet, I would guess).
You would have to get the specs of the chips to find out whether
hardware acceleration is even a possibility, and then approach the
crypto providers (e.g. Oracle, OpenSSL) with questions about how to
enable those hardware-supported routines.
