Hello, Zigor, It is interesting to know the end of the story :)
We also have application on Mina2.0.4 in the latest test we reached almost 100 Mbit output from a single server on 1GBit network We transfer about 40KBytes per query and have about 90 000 queries processed in 5 minutes However to execute the query some data must be read from disk, so maybe that speed is ok
