No …我正在实现一个需要序列化和反序列化大对象的程序,所以我正在进行一些测试pickle,cPickle并marshal选择模块来选择最佳模块.一路上我发现了一些非常有趣的东西:
我正在使用dumps然后loads(对于每个模块)列表中的dicts,元组,整数,浮点数和字符串.
这是我的基准测试的输出:
DUMPING a list of length 7340032
----------------------------------------------------------------------
pickle => 14.675 seconds
length of pickle serialized string: 31457430
cPickle => 2.619 seconds
length of cPickle serialized string: 31457457
