Actually you can enable the compression for regular postback as explained here
. I strongly suggest that you examine this
blog post in which you can find helpful information regarding the ViewState compression. Also more general information about compression ratio can be found here.
Note that when RadCompression is enabled the ViewState is compressed by default. You can however compress only it as explained in the first linked article under the ViewState compression section.
Additionally for your convenience I have created a video(link here
) which illustrates the difference in the compressed and uncompressed response. In attachments you can also find the test sample used for creating it.
