问题：nutz在解析multipart 
的请求时，解析请求，存储file到临时文件夹的效率有
待提升。

检验方法：

测了一下,的确比较慢.
开头用了一个50M的文件,结果一直在跑,还以为死循环了.
然后改为一个2m的文件, 耗时十几秒吧.

晚上再详细测测.

r997 修改测试代码后, 性能问题可以说是不存在的了.

对于 Uploading， 应该支持在 Mvc 中配置 BufferedStream 的缓冲大小
即，在 UploadAdaptor 的构造函数中，添加一个缓冲区大小

采用了 FastUploading， 成块读取和写入字节，速度提高了将近 
1倍

fixed in r1073,r1074

SimpleUpload,依旧需要180s左右.

的确是显著提高!!
