So I have this dual 16-core Opteron Dell R715 with 128G of RAM attached to a SuperMicro disk enclosure with 45 2TB Toshiba SAS drives (via two LSI 9200 controllers and MPxIO) running OpenIndiana 151a4 and I''m occasionally seeing a storm of xcalls on one of the 32 VCPUs (>100000 xcalls a second). The machine is pretty much idle, only receiving a bunch of multicast video streams and

...ue of ARC kstats as they change over time. This is similar to the ideas behind mpstat, iostat, vmstat, and friends.

Today I updated the firmware on my StorageTek 2540 to the latest recommended version and am seeing radically difference performance when testing with iozone than I did in February of 2008. I am using Solaris 10 U5 with all the latest patches. This is the performance achieved (on a 32GB file) in February last year: KB reclen write rewrite read reread 33554432

Hi all, I have exchanged my Dell R610 in favor of a Sun Fire 4170 M2 which has 32 GB RAM installed. I am running Sol11Expr on this host and I use it to primarily serve Netatalk AFP shares. From day one, I have noticed that the amount of free RAM decereased and along with that decrease the overall performance of ZFS decreased as well. Now, since I am still quite a Solaris newbie, I seem to
