Social icon.png load times

The file sizes seem right to me. Those are 2kB images. We've tried to make them extremely small as it is.

Combining them into a sprite is likely going to be difficult since it conflicts with our ability to let you use a custom image for each tag. By default, we distribute an icon.png and icon_label.png file for each provider (one is just the logo, the other is the log with text). In the SCLogin module and in the JFBConnect parameters, we let you select a different image altogether which would not work easily with a CSS sprite file.

If you wanted to, you could use some CSS and create a sprite file yourself if you know what image you're always using. However, Cloudflare is doing it's job from your picture by setting the expiration date for those images about 5 days in the future. The very first hit to your page will take a little longer to load those images, but subsequent refreshes or navigation through your site shouldn't have any impact because the assets are cached in the browser already.

I hope that helps explain a little more about their purpose though there's no real substance I have for improving things because what you have above seems right.
