I'm using nxp s32v234 for multi-core parallel testing but have noticed a performance drop when running dual-core under the same cluster compared to single-core runs, and no drop when running with all cores. The test is each core running a separate application at the same time, The problem is that the performance degradation appears when running dual cores in the same cluster but disappears when running all cores. I'm assuming it could be an issue with the app itself used for testing or a component that plays a role in synchronising when running on multiple cores. Can anyone help me with this?
