My website is sometimes loading very slowly. It does not happen every time I try to load it. When it occurs, I see "i0.wp.com..." in the lower-left corner of the (Chrome) browser. 

Any help or suggestions would be greatly welcome.

Cursory searches online seem to suggest that "i0.wp.com..." might be related to Jetpack site accelerator.

Sometimes, my site never fully loads. It will time out before loading, as if the loading process is fully resolved, but actually parts of the webpage will be missing. 

My site is small, a brand-new blog.

Thank you!

P.S., I realize this problem may not be related to TheGem, but since I am not sure, I wanted to open a CodexThemes ticket first.

Thank you, Oliver! I will look over that information. Also, the site has been loading faster the last several days.

You may fully close this ticket. I will try the optimization recommended in the documentation.
