%description

The Storage Performance Development Kit (SPDK) provides a set of tools and libraries for
writing high performance, scalable, user-mode storage applications. It achieves high
performance by moving all of the necessary drivers into userspace and operating in a
polled mode instead of relying on interrupts, which avoids kernel context switches and
eliminates interrupt handling overhead.
