Welcome in this video
I want to talk about content caching on the Mac content caching is a service that you can enable to cache
Downloaded content from apple services like iCloud app downloads updates things like that
And I have a couple articles that talk about content caching
I'll put a link in the description to these articles
This first one talks about what is content caching and and then it talks about how it works
so if you have for instance two iPhones and
One of them downloads a system update. It will go through the content cache
the content cache will look at its cache and see if it has that update and if it doesn't it will download it through the
Internet and store it in the local cache and then send it to the phone
Then the second phone that connects will ask the cache for the update and the cache will have the update
He'll send it right down to the phone. So it doesn't have to go out over the public Internet
So this would mostly be useful for
applications where you have multiple devices
so in our house
We have probably a half dozen iOS devices and a couple Mac's it wouldn't be it's not the most ideal situation for using cache
But it does help a little bit as I'll show in just a minute here
this would really be helpful for a school or
Say a hotel if you want to cut down your bandwidth or just even provide a service to your customers
Or the people on the network this next article has the content type supported by caching service
So it has a split apart by Mac OS it does the Mac OS updates and Internet recovery images
so this internet recovery image is interesting because if you support multiple Macs and you're using the
Recovery system where you download the image from the internet?
This will speed that up
If you're dealing with Mac OS 10 dot 13.5 or later this way you download it
Once it caches it the next time it does it quickly because that can take quite a while
It also does apps and app dep updates from the Mac App Store
GarageBand downloadable content iCloud data caching photos and documents and Apple books content
That's on Mac OS and then iOS 7 and later and Apple TV
it does iOS updates Apple TV updates iOS apps
Apple TV apps and app updates on demand resources for iOS 10 and later and TV OS 10 and later the iCloud data caching photos
and documents for iOS 9 so if you have multiple devices
That are downloading say photos and documents that will speed that up which could be pretty handy
Especially if you have like a phone an iPad a couple Macs things like that
And then the iTunes U course
materials and
Apple book content and
certain mobile assets such as Siri high quality voices language dictionaries and more that article kind of tells you what is cached and
Then this third article talks about statistics on caching
So what I'll do next is show you how it's enabled
if you go to the system preferences and open that up and click on sharing you'll see content caching down here is an item and
You just check that now if you're using an old Mac an old system, you can enable it you can buy Mac OS server
which is like 20 bucks in the App Store and then you can enable content caching using that but if you can update to
Mojave I think high sierra also had this then you can enable content caching there too for free
You don't have to buy the the server you have an option here
It says cache all content or only shared content or only iCloud content
so if you choose shared content, you'll see it says store shared content such as apps software updates on this computer and
If you choose iCloud content, it says store iCloud content such as photos documents on this computer
So I've chosen all content and then options here
You can choose your how much you want. So you can do this slider here. So I have 102 gigabytes and it says I'm using
43.8 seven days and then you can reset that. So I'll hit cancel there. So I've already had this set up
I'm not setting it up new and then if we go to
Activity Monitor and
This is where you look at how much CPU and memory is being used by your system
If you have caching enabled you'll see a little cache tab over here. And if you hit that it give you statistics here
So it'll say in the last hour last 24 hours last seven days and last 30 days
We look over the last 30 days here. It's the data served to clients and it served up the
15.98 the data served from cache was 6.47
So it's about a third of the data has been served up from cache and then you know
Nine point five two has been served from the Oregon which meaning it means it was downloaded
So, you know, I'm gaining six point four seven here
it's not a tremendous and but I have the
Computer it's running
I might as well just turn it on and I have the storage on the computer now if you are
in a school for instance
you might actually
buy a Mac Mini and set it up for this and you just max out the cash if you're doing that if you're just using
It for caching
Probably the best thing to do would be to find a used mat and just tuck it in a corner turn it on turn caching
on and have it do the caching for you like an old Mac Mini would be perfect for this and
You could even hook in a bigger hard drive if you wanted to store, but you'd probably want to monitor how much you're using
They do recommend using the computer connected to Ethernet - Gigabit Ethernet. You can also plug in two computers or more
Yeah, you can use multiple computers and it's it they talk about in this document here
Like if you're on different networks, you can like right here
It says can I have more than one content cache you can hook in multiple computers and they'll talk to each other and work together
You can set these up on a more complicated networks - there's command-line options and things like that once you dig into it
I'm just talking about the basics of caching in this video. This is all I have for you guys on content caching
