5510 z1 core code runs more slowly if z0 core started

I have found that the code in my z1 core runs about half as fast if I start the z0 core. Even with an empty loop running in the z0 core.The z0 core is not generating any interrupts or exceptions and the only interrupt occurring in the z1 is the PIT I have coded.

 

Has anyone else found this? Does anyone know why it happens? I've been through the manuals and can't find an explanation.

 

Thank you, Mark
