While updating packages on our CentOS server I got the following message:

Downloading packages:
Delta RPMs disabled because /usr/bin/applydeltarpm not installed.

Do I need to do something about that? Should I just ignore this?

You don't need to do something, but you can, especially if you have a slow internet connection. If you install deltarpm support:

yum install deltarpm

you will download only the differences with older versions of already installed packages. This is done at the cost of increased processing time.
