Hi, I''m trying to use dtrace to signal threads in my app when certain events happen, and the raise() action seemed adequate -- looking at the kernel sources, it sends a signal to the currently executing thread, and a quick microbenchmark confirmed this. However, further testing showed that if lots of threads hit the event simultaneously, the signal only gets delivered once, and may also

Folks, Perplexing question about load average display with prstat -Z Solaris 10 OS U4 (08/07) We have 4 zones with very different processes and workloads.. The prstat -Z command issued within each of the zones, correctly displays the number of processes and lwps, but the load average value looks exactly the same on all non-global zones..I mean all 3 values (1,5,15 load averages) are the same which is quasi impossible given the different workloads.. Is there a bug here? Thanks, -Nobel

It seems we are hitting a boundary with zfs send/receive over a network link (10Gb/s). We can see peak values of up to 150MB/s, but on average about 40-50MB/s are replicated. This is far away from the bandwidth that a 10Gb link can offer. Is it possible, that ZFS is giving replication a too low priority/throttling it too much?

Hello, when I run ''zfs send'' into the file, system (Ultra Sparc 45) had this load: # zfs send -R backup/zones at moving_09112009 > /tank/archive_snapshots/exa_all_zones_09112009.snap Total: 107 processes, 951 lwps, load averages: 54.95, 59.46, 50.25 Is it normal? Regards, Jan Hlodan
