Does that seems a bit excessive?
Yes, it is. If there is a lot of I/O, this might be due to the
thread pool used for I/O.
This is why I wrote the linux-aio patch. It only reduced CPU
consumption by about 2% although I'm not sure if that's absolute or
relative. Andrew?
Was that before or after the entire path was made copyless?
Before so it's worth updating and trying again.
