为什么需要在struts中指定缓冲区大小？

Question

<result name="success" type="stream">
        <param name="contentType">image/jpeg</param>
        <param name="inputName">inputStream</param>
        <param name="contentDisposition">filename="${filename}"</param>
        <param name="bufferSize">1024</param>
</result>

When we download files using struts, What is the need of specifying buffer size? What is it use?

Answer 1

The size of the buffer affects the processing efficiency of the program. In general, only 1024 should be used.
