simple and faster {,un}serializer for most python builtin data objects

Project description


simple {,un}serializer for several python builtin objects (None/True/False/int/long/float/str/list/tuple/dict/set)

this extension runs much faster than builtin python serializers like marshal and cPickle.


This extension uses a fix-length buffer in dumps, which has a default length of 64KB. Call fserial.setbufsize to set a larger lenghth, in case the result may exceed the default value.

Performance test:

you can try yourself.

Time consumed for 5,000,000 rounds of dumps/loads:

fserial.dumps: 1.581582
marshal.dumps: 5.548474
cPickle.dumps: 5.602932
simplejson.loads: #approximate 10x slower than cPickle/marshal

fserial.loads: 3.616863
marshal.loads: 6.749527
cPickle.loads: 15.953505
simplejson.loads: 23.159412
