Cap'n Proto - Insanely Fast Data Serialization Format Copyright 2013-2015 Sandstorm Development Group, Inc. https://capnproto.org Cap'n Proto is an insanely fast data interchange format and capability-based RPC system. Think JSON, except binary. Or think of Google's Protocol Buffers (http://protobuf.googlecode.com), except faster. In fact, in benchmarks, Cap'n Proto is INFINITY TIMES faster than Protocol Buffers. Full installation and usage instructions and other documentation are maintained on the Cap'n Proto web site: http://kentonv.github.io/capnproto/install.html WARNING: Cap'n Proto requires a modern compiler. See the above link for detailed requirements. To build and install (from a release package), simply do: ./configure make -j4 check sudo make install The -j4 allows the build to use up to four processor cores instead of one. You can increase this number if you have more cores. Specifying "check" says to run tests in addition to building. This can be omitted to make the build slightly faster, but running tests and reporting failures back to the developers helps us out!
