Yep, kernel appeared to be mostly idle while you produced that kernel profile. It seems you're using compressed zfs filesystems (-> lzjb_compress). And some time is spent allocating anonymous memory (-> anon_*, maybe bcopy, kcopy, hwblkclr -- I/O on a tmpfs, perhaps?) Did you produce that profile while you observed ~50% kernel cpu time usage? I think not. > Anyway we found that kernel load appears doing I/O. > We have localstorage on UFS and ZFS pools on a SAN. > > The system load seems to be related to I/O access on ZFS pools. So, try to put some heavy I/O load on the ZFS pools and rerun the kernel profile.
