processing overhead, while improved locking allowed it to
scale up to at least 40 processor cores without significant

optimizations that allowed to increase peak NFS request

<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>
