iMX6 Java optimizations

robertopierpaol — Thu, 12 Jan 2017 12:01:01 GMT

Hi,

we are developing Java8 software in a Linux-on-iMX6 environment and we have read a quite old post All Boards Java‌ about the advantages of using "Oracle Java SE Embedded" over the iMX* architectures.

We are currently using "Oracle Java SE 8 for ARM" (not the SE Embedded) with good outcomes.

Following the afore mentioned post we have made some tests with the SE Embedded 8 version for ARMv7, keeping the same Java program on the same hardware, but we haven't noticed any relevant improvement in the performances: are we missing something?

We haven't re-compiled the Java program, we just changed the JVM: may this be the mistake? Should we use a special Java compiler to leverage any optimization of the iMX architecture?

We didn't find any clear explanation on this topic on the Internet, that's why we are writing here.

Thanks in advance,

Roberto

Hello,

The example of the https://community.nxp.com/docs/DOC-1478 is relatively simple, hardly

great optimization may be gotten here.

Also, note, it is needed to use hardware accelerators in software

for optimization, but standard Oracle VM for ARM is applied in the case.

Please apply to Oracle for implementation details.

Have a great day,

Yuri
