I got a strange feedback from F5 support, this is a normal behavior that the ASM uses CPU7 !
Regarding the high CPU 7 usage,
The high CPU on the last core ( in this case core 7) is a frequently reported concern from many customers. The CPU usage here is misleading- it is high because many ASM processes are pinned to that core for GUI performance reasons. This was done after much testing by developers ; the associated with ID432080. By pinning ASM processes to a single CPU, the processes benefit from local processor caching and communication overhead.
That said, F5 PD is well aware that the high CPU usage reporting is worrying here needlessly. They have made some changes in 11.5.1 hotfixes and in 11.5.2 to improve the CPU reporting, specifically with regard to AVR spiking the CPU on the last core every 5 minutes (again, expected behavior; ASM leverages AVR for its reporting) but these changes have not been ported to 11.6.0 yet.
I have escalated the issue, as we are not able to access some features in the ASM GUI due to the High CPU.
