Hi All,
I have ported openjdk-8-72b05(from Yocto) for both armv7 and aarch64 architectures. I am sharing sample code via link, which I have run to see the crypto performance and found it is very slow compared to OpenJDK-7.

Hi Ningsheng,
I am very glad for your quick response. Thank you.
Issue exists on both armv7 and armv8. I have checked the patch on armv8 and it looks pretty old patch. attaching one file for your reference.
My issue is on armv7 platform . Could you suggest how can I go forward to have good performance?
Thanks, Srinivas.

Hi Srinivas,
Your file looks identical to current aarch64-port jdk8u master branch.
I am not sure about current armv7 status. You can ask it on the list: arch32-port-dev@openjdk.java.net.
For armv8 aarch64, I ran your test on my Cortex-A57 based system with latest openjdk8u, the time result is:
real 0m4.049s user 0m6.080s sys 0m0.624s
It looks much better than your result.
If this issue also exists in your armv8 platform, can you please try the following command line:
$ java -XX:+UnlockDiagnosticVMOptions -XX:+PrintIntrinsics -cp common-0.0.1-SNAPSHOT.jar:jars/* com.ericsson.athena.common.certificate.Main
to check whether crypto related intrinsics are implemented in your port. E.g. part of my output:

------------------------
You can find that some sun.security.xxx are intrinsified. They will use ARMv8 crypto extension. However, armv7 does not have such hardware crypto support.

Hi Ningsheng,
I am very glad for your quick response. Thank you.
Issue exists on both armv7 and armv8. I have checked the patch on armv8 and it looks pretty old patch. attaching one file for your reference.
My issue is on armv7 platform . Could you suggest how can I go forward to have good performance?
Thanks, Srinivas.

Hi All,
I have ported openjdk-8-72b05(from Yocto) for both armv7 and aarch64 architectures. I am sharing sample code via link, which I have run to see the crypto performance and found it is very slow compared to OpenJDK-7.
