-----------------------------------------

What would you consider an appropriate buffer size?  Are you suggesting it be configurable?

> The buffer size is fixed as 1024 bytes. With the size of the data varies, the performance
can be damaged a lot.
> We need an appropriate buffer size which depends on the size of the data to be copied.
> This is the same as the Appache Bug (https://issues.apache.org/bugzilla/show_bug.cgi?id=32546)
