=== adam_g is now known as adam_g_out [19:40] We'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] Any ideas? [21:18] jerryt: 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?
