SPDY is the new protocol proposed by Google to complement problems of HTTP(Hypertext Transfer Protocol)/1.1 and to improve web speed. In this paper, we evaluated the performance of SPDY protocol in a variety environment. By this evaluation, we examined the characteristics of the SPDY protocol and compared the differences between the existing protocol and SPDY protocol. And we took a closer look at the Flow Control of SPDY. Through this, we analyzed the problem of SPDY. It improved performance at 3G network environment, but failed to improve performance at high speed WLAN and mobility environments. We also verified that Flow Control does not work well. And finally we proposed directions for improvement of this protocol.
