[zeromq-dev] Considering zeromq for project at Microsoft but have some questions on throughput behavior

[Steven McCoy]

I meant 29West have a CIL API for LBM/UMS that supports zero-copy:


   - Zero Object Delivery (ZOD) has been implemented for .NET, which allows
   .NET messaging receivers to deliver messages to an application with no
   per-message object creation.
   - Zero Incoming Copy (ZIC) has been implemented for .NET, which provides
   access to message data directly through a byte pointer returned by the
   LBMMessage.dataPointer() method.
