+ \subsection{Hardware acceleration}
+ ClamAV 0.90 comes with support for Sensory Networks' NodalCore
+ acceleration technology. Thanks to specialized Security Processing Unit
+ built into NodalCore C-Series accelerators it is possible to achieve more
+ performance than is possible by just adding general purpose CPUs.
+ Additionally, Sensory Networks' CorePAKT technology ensures that compiled
+ signature databases occupy a memory footprint smaller than any other
+ competing technology on the market - in many cases by up to 90\%. The
+ ability to store multiple databases in compressed format whilst still
+ achieving high throughputs makes NodalCore ideal for applications
+ demanding high performance on large signature databases such as ClamAV.\\
+ For more information please visit \url{http://www.clamav.net/nodalcore/}
