Andrew Steinborn 821a7a45bc Small optimization for NativeVelocityCipher 
Instead of going through the general process function, which does extra
checks to ensure that its arguments are sane, move "closer" to the action
by stripping down to the actual implementation.

velocity-natives

This directory contains native acceleration code for Velocity, along with traditional Java fallbacks.

Compression

  • Supported platforms: macOS 10.13, Linux amd64 (precompiled binary is built on Debian 9 with JDK 8)
  • Rationale: Using a native zlib wrapper, we can avoid multiple trips into Java just to copy memory around.

Encryption

  • Supported platforms: macOS 10.13, Linux amd64
  • Rationale: Using a C library for encryption means we can limit memory copies. Prior to Java 7, this was the only way to use AES-NI extensions on modern processors, but this is less important since JDK 8 has native support.
  • Note: Due to U.S. restrictions on cryptography export, this native is provided in source code form only for now.

OS support

If you are on Alpine Linux, apk add libc6-compat will enable native support.
