Fast .Net Serializer (based on https://github.com/tomba/netserializer)
#####New features in NetSerializer2:
-
The next types were added to list of supported serialization types: (via WritePrimitive/ReadPrimitive) Nullable, TimeSpan, DateTimeOffset, decimal, Guid, int[], ArrayList, BitArray, HashTable, Queue, Stack, SorrtedList List, HashSet, Queue, Stack, SortedDictionary<K,V>, SortedList<K,V>, SortedSet, ConcurrentDictionary<K,V>, ConcurrentBag, ConcurrentQueue, ConcurrentStack, BlockingCollection, LinkedList
-
generated of fly version SerializationSwitch/DeserializationSwitch was replaced with using delegates and DynamicMethods.
-
serialization/deserialization of objects with circular links was added. New method SerializationDeep, DeserializationDeep
-
new object may be added to Serializer later after initialization with method Serializer.Register(...)
-
Serialization state maybe stored(restored)
-
You may create two(and more) different Serializers(with different settings) in a one application. But note, you must decide at first, if you really need it. It is a very special thing.
#####Performance
Below is a performance comparison between NetSerializer2, NetSerializer and protobuf-net.
NetSerializer the original project - https://github.com/tomba/netserializer .
Protobuf-net is a fast Protocol Buffers compatible serializer.
The table lists the time it takes run the test, the number of GC collections (per generation) that happened during the test, and the size of the outputted serialized data (when available).
######There are three tests:
-
MemStream Serialize - serializes an array of objects to a memory stream.
-
MemStream Deserialize - deserializes the stream created with MemStream Serialize test.
-
NetTest - uses two threads, of which the first one serializes objects and sends them over a local socket, and the second one receive the data and deserialize the objects. Note that the size is not available for NetTest, as tracking the sent data is not trivial. However, the dataset is the same as with MemStream, an so is the size of the data.
The tests are ran for different kinds of datasets. These datasets are composed of objects of the same type. However, each object is initialized with random data. The types used in the datasets are:
- U8Message - contains a single byte field, initialized always to 0
- S16Message - contains a single short field
- S32Message - contains a single int field
- U32Message - contains a single uint field
- S64Message - contains a single long field
- PrimitivesMessage - contains multiple fields of primitive types
- DictionaryMessage - contains multiple fields of dictionary types
- ComplexMessage - contains fields with interface and abstract references
- StringMessage - contains random length string
- StructMessage -
- BoxedPrimitivesMessage -
- ByteArrayMessage - contains random length byte array
- IntArrayMessage - contains random length int array
The details of the tests can be found from the source code. The tests were run on a 64bit Windows 8 box.
