+ <p>The &os; RPC stack, used as base for its NFS server, took
+ multiple optimizations to improve its performance and SMP
+ scalability. Algorithmic optimizations allowed to reduce
+ processing overhead, while improved locking allowed it to
+ scale up to at least 40 processor cores without significant
+ lock congestion. Combined with some other kernel
+ optimizations that allowed to increase peak NFS request
+ rate by many times, reaching up to 600K requests per second
+ on modern hardware.</p>
+
+ <p>The CAM Target Layer (CTL), used as base for new kernel
+ iSCSI server, also took series of locking optimization,
+ that allowed to increase its peak request rate from ~200K
+ to ~600K IOPS with potential of reaching reate of 1M
+ request per second. That rate is sufficient to completely
+ saturage 2x10Gbit Ethernet links with 4KB requests. For
+ comparison, the port of net/istgt (user-level iSCSI
+ server) on the same hardware with equal configuration
+ shown only 100K IOPS.</p>
+
+ <p>There is also ongoing work on improving CTL functionality.
+ It was already made to support 3 of 4 VMWare VAAI storage
+ acceleration primitives (net/istgt supports 2), while the
+ goal is to reach full VAAI support during next months.</p>
+
+ <p>With all above, and earlier improvements in CAM, GEOM, ZFS
+ and number of other kernel areas coming soon FreeBSD 10.1
+ may become the fastest storage release ever. ;)</p>
