...ore so because it uses Int32 in places. However, the code in RNG.c (RNG_Init) says ns = *((int *) User_unif_nseed()); if (ns < 0 || ns > 625) { warning(_("seed length must be in 0...625; ignored")); break; } RNG_Table[kind].n_seed = ns; RNG_Table[kind].i_seed = (Int32 *) User_unif_seedloc(); consistent with the earlier definition of RNG_Table entries as typedef struct { RNGtype kind; N01type Nkind; char *name; /* print name */ int n_seed; /* length of seed vector */ Int32 *i_seed; } RNGTAB; This suggests that the type of user_unif_s...

ZFS-Performance: Raid-Z vs. Raid5/6 vs. mirrored
Hi list, as this matter pops up every now and then in posts on this list I just want to clarify that the real performance of RaidZ (in its current implementation) is NOT anything that follows from raidz-style data efficient redundancy or the copy-on-write design used in ZFS. In a M-Way mirrored setup of N disks you get the write performance of the worst disk and a read performance that is
