jerrytWe're running a Dell server with hardware raid.  When we do IO operations such as extracting a large tar file a kworker process pegs IO at 99% or so.  pref points to cpu_startup_entry 19:40
jerrytAny ideas?19:40
JanCjerryt: obvious question: is that real hardware RAID or fake hardware RAID which relies on the drivers/CPU to do the hard work? also: how large is the tar file compared to RAM?  and does it use compression and/or encryption?21:18
