• Autobahn tests all pass.
• One million WebSockets require ~111mb of user space memory (104 bytes per WebSocket).
• Single-threaded throughput of up to 5 million HTTP req/sec or 20 million WebSocket echoes/sec.
• Linux, OS X, Windows & Node.js support.
• Runs with raw epoll, libuv or ASIO (C++17-ready).
• Valgrind & AddressSanitizer clean.
• Permessage-deflate, SSL/TLS support & integrates with foreign HTTP(S) servers.
• Multi-core friendly & optionally thread-safe via compiler flag UWS_THREADSAFE.

First of all you need to install the required dependencies. This is very easily done with a good open source package manager like Homebrew for OS X, vcpkg for Windows or your native Linux package manager.

• OpenSSL 1.x.x
• zlib 1.x
• libuv 1.3+ or Boost.Asio 1.x (both optional on Linux)

If you wish to integrate with a specific event-loop you can define USE_ASIO or USE_LIBUV as a global compilation flag and then link to respective libraries. USE_EPOLL is default on Linux while other systems default to USE_LIBUV.

• Fedora: sudo dnf install openssl-devel zlib-devel
• Homebrew: brew install openssl zlib libuv
• Vcpkg: vcpkg install openssl zlib libuv and/or vcpkg install openssl:x64-windows zlib:x64-windows libuv:x64-windows

• make
• sudo make install (or as you wish)

• Compile VC++.vcxproj with Visual C++ Community Edition 2015 or later.
