OptaPlanner on Solaris is slower 5 times than on Linux os

I have been running OptaPlanner application on Linux servers which takes total 10 minutes. However, when I move it to run on Solaris server the total processing time become more than 50 minutes. And the Solaris(SPARC-T5) has more CPUs and memory than Linux(Intel).

So, I am wondering is there any settings to be done to use OptaPlanner on Solaris os? What can be the possible reasons for this issue?

Thanks in advance for your time and answers.

Interesting observation - I 'd like to understand what happens there too.

Create a benchmark config for your use case (if you haven't already), run it on both machines and share both benchmark html reports here. I'll diagnose them.

Typical causes can be: JDK version differences, JVM -server mode, undetermined termination config (unimprovedTimeLimit), ... But none of that explains a 5x difference.
