...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
