Some settings I would recommend:
******************************************************* * ZFS settings: * Manage memory use between ZFS and applications set user_reserve_hint_pct=80 * Determines the minimum size of ZFS ARC * default: 1/32nd of physical memory or 64 Mbytes, whichever value is larger. set zfs:zfs_arc_min=0x100000000 * Change number of CPUs dedicated to ZFS ZIO bulk processing * Default was 100%, now 50%, usefull if ASM needs the power, not ZFS set zfs:zio_taskq_batch_pct=10 * Sol 11.3 - Runnable Thread Occasionally Stays in Run Queue for a Longer Period (17697871) set thread_transience_user=0 set thread_transience_kernel=0 * Controls the logical block size used by NFS client. * This represents the amount of data the client attempts to r/w * to the server when it needs to do an I/O. * Default = 32k set nfs:nfs3_bsize=1048576 set nfs:nfs4_bsize=1048576 * Controls the number of TCP connections that the NFS client uses * Default = 1 set rpcmod:clnt_max_conns=8 * Specify the amount of kernel pageable memory available. * Increasing the default (2g) allows either larger kernel thread stacks * for the same number of threads or more threads. set segkpsize=6291456
