+	 <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>
