<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>
