What is Service Host Delivery Optimization?

Delivery Optimization is a cloud-based, peer-to-peer (P2P) technique introduced by Microsoft to make downloading Windows updates and apps from the Microsoft Store much faster. Instead of getting updates from just one place, Delivery Optimization allows your PC to get the updates from many places all at once.

This can be from Microsoft’s own servers, computers nearby on your network, or even PCs across the internet downloading the same stuff. This method is very efficient because it uses all these sources to speed up the download process.

But, this feature comes with a catch. It can make your network usage high, especially if your internet isn’t the fastest to begin with. We’ll talk more about why this happens next.

Why Delivery Optimization causes high network usage

1. Peer-to-peer sharing

With Delivery Optimization turned on, your PC can share updates with other computers. This might be with computers in your place or, depending on your settings, with PCs over the internet.

This sharing method, while it sounds like a great deal, it can cause your internet to get very busy. If many devices are getting updates from your computer at the same time, your network use, mainly upload speed, will go up.

2. Downloading from multiple sources

A big thing about Delivery Optimization is that it can grab updates from different places at the same time. This is, of course, good for the download speed but also means that you’re using more of your internet bandwidth at once, leading to higher network use. However, this is totally normal.

3. Frequent updates

Another reason for high network usage is just how often updates come out. Windows 11 needs regular updates for bug fixes, security patches, and new features. Apps from the Microsoft Store can also get updated frequently. The more updates there are, the more your network gets used.

By turning off Delivery Optimization, you’re stopping the peer-to-peer sharing. But note that your updates and app downloads might slow down since they’ll only come from Microsoft’s servers now.

Here’s what I think

Delivery Optimization in Windows 11, brought over from Windows 10, is meant to speed up downloading updates and apps. But it can also lead to higher internet usage because of its peer-to-peer sharing, getting files from lots of places at once, and the frequent updates.

If you need to, you can completely turn off Delivery Optimization. Just know that turning it off might slow down your downloads since everything will come straight from Microsoft’s servers. Try out different settings, see what your network can handle, and pick what works best for you.
