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,
Does your openjdk contain this path?

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.
