+      Very fast lossless compression algorithm, providing compression speed
+      at 400 MB/s per core, with near-linear scalability for multi-threaded
+      applications. It also features an extremely fast decoder, with speed in
+      multiple GB/s per core, typically reaching RAM speed limits on
+      multi-core systems.
