 ## Features
 
 - Plain old protocols with no built-in support for authentication or encryption.
-- Top class processor/memory/storage/bandwidth efficiency.
+- Highly efficient, written in C.
 - Lua scripts powered rule set.
 - Routing connections by rule and even building an autonomous proxy mesh.
 - Horizontally scalable.
