If you are on WiFi, then could be normal.

As WiFi is subject to interference and long periods of delays. Also, facebook can delay seconds as things work themselves out. I know folk that are newer to computers and the internet and every little delay they are posting on forums and calling their internet providers. It's working, just not as well as folk want.
