Install
If you plan use lzmq.threads module then you should also install llthreads2
-
Using LuaRocks:
luarocks install lua-llthreads2orluarocks install lua-llthreads2-compat
luarocks install lzmqor install only ffi versionluarocks install lzmq-ffi -
Using LuaDist:
luadist install lua-llthreads2orluadist install lua-llthreads2-compat
luadist install lzmqorluadist install lzmq-ffi
API
This is short API description.
See also exampes from OMQ - The Guide.
Performance
To run same test you should copy original performance tests to exampes/perf2/libzmq
and run runner.lua from exampes/perf2. For now it require LuaJIT and exists
C and FFI version of lzmq library.
Of course you can run any test manually.
