在GWT中将大型阵列从服务器传输到客户端

I'm attempting to transfer a large two dimensional array (17955 X 3) from my server to the client using Asynchronous RPC calls. This is taking a very long period of time which is especially bad because the data is needed in order to initialize the application. I've read that using a JSON object might be faster, but I'm not sure how to do the conversion in Java as I'm pretty new to the language and GWT, and I don't know if the speed difference is significant. I also read somewhere that I can zip the data, but I only read that in a forum and I'm not sure if it's actually possible as I couldn't find information for it elsewhere. Is there any way to transfer large amounts of data from server to client? Thanks for your time.I'm attempting to transfer a large two dimensio
