Hi,

 

 

I opened the case... Based on my experience, medium (25%) sustained CPU loads are not rare on devices using ASM, with not too high traffic loads. 50% looks something strange, although I think v.9.4.8 has something to do with that... I know in v.10.2 ASM performance has been greatly improved.

 

 

I hope support would tell me where to look to solve this issue. I'll get back if I find a solution.
