15. Summary
DAQ-Middleware is being employed in 8 experiments at MLF J-PARC
The new development team formed under Open-It in April 2010
We released DAQ-Middleware version in August 2010
The source/sink type template generator reduces development efforts.
The throughput between two components via Ethernet is now 80MB/s (the previous: 45MB/s)
