Eric Evans commented on CASSANDRA-1765:
---------------------------------------

The Avro tests are unnecessarily serializing and deserializing their own schema 
as part of the messages. In real life both reader and writer would have the 
schema, readers/writers would store it (once)/read it, to/from the file format, 
or handshake it (once) on an RPC session.

The attached patch (v1-0001-CASSANDRA-1765-don-t-ser-dser-schema-string.txt) 
fixes this.

Results run on my laptop here: https://gist.github.com/2f5d00d87c77260bcaac

These results are averages of the 5 tests ran. One thing interesting about the 
Avro results is the high/low swing on the serialization times that make up the 
average. About half the runs are ~2175, and about half ~1200.  It'd be 
interesting to find out why that is, 2175 would make it the slowest by a wide 
margin, and 1200 the fastest by a wide margin.
