Why is that updates have to be about 10 GB of data. I have 200 mbps internet connection (did a speed check) and update download (by flight simulator) is happening at 5 mbps, and I am guessing back-end server is slow.
This is very annoying.
Microsoft, can you please work on optimizing the updates?
Why not ?? It is OK for me…
cheers 
World data on the servers alone is 2,000,000 GB.
Given the size of the world and the details I think the updates are of reasonable size.
There is something called delta
The core software and it’s support files to make the game world work are large in size.
Model are stupidly high details and large in size.
The code behind each plane and its avionics are huge due to complexity.
Textures are ridiculously high res and large in size.
Asobo hand-crafted airports are very detailed and large in size.
Why would you expect small updates when all of that is huge?
This isn’t 2010 any more. 10+GB isn’t considered to be a large amount of data any more. I can understand this may be an issue for some people without access to higher speed internet. But relatively speaking, this game is big, but not out of the league of other AAA titles.
You want large? Try buying a PS5 and downloading games on that.
Yes. I have PS4 and other GB’s downloads I have done had been very fast. If the backend server is slow, that is problem not from my side.
If they have to share such large data, which is understandable, they either come with new and better compression system or make sure download server pipe is bigger and doesn’t get choked. I tried yesterday night and today morning it is still downloading 
I always get 500 mbps on my 500 mbps lines. The lines are never choked. It’s a known problem that some computers can’t reach the desired speeds. Search the forum for many topics and possible solutions.
updates aren’t 10GB, the last one was 1,4GB, and downloaded at my maximum bandwidth.
Thanks for the thought 
. I think, I know how performing my computer is. I just validated by downloading a @1.5 GB image.
As the msfs2020.exe uses excess cpu power (even in main menu, for whatever reason…), your cpu may not be able to procss the incoming data…
Set process priority higher in taskmanager. This helped me.
Mine is showing about 10GiB. May be I am behind as I didn’t use FS for a month or so. But in past updates have been quick to download.
Just checked.
Flight Simulator: 6-8% CPU and 2GB memory.
Overall: 14% CPU and 25% memory ( of 64GB)
Unless GPU is limiting it.
I have 250 mbps internet connection and 10gb data has never taken any longer than a couple of minutes to download for me, I have Steam version, there must be some problem with your internet provider.
No, you don’t. That doesn’t say anything. The content servers of MSFS have a funny setting which some PCs can’t handle and that will result in very low download speeds.
What also doesn’t help is the fact that the updater still uses 100% GPU when not frame-limited. This also results in funny download behavior because of system interrupts. Try to limit the FPS to 30 or 60 and see if things improve.
Alternatively, you can try and change this setting:

Its not just your computer/internet speed that plays here!
you have issues like:
Yes. I just noticed that GPU loaded to 100% and not sure why it has to be that way. I noticed that update picked up the speed up to 100Mbps. Once part of download was complete and decompression done, it slowed down again
I never had any issue downloading MSFS updates in the past.
I will let download happen at its pace as I am not using that computer right now. I will try that tip if the update doesn’t finish by evening.
Could you please elaborate on this so-called “funny setting” on MSFS content servers , please. Thank you.
People complain about everything and for no reason. We should be happy that the developers are releasing the updates at a very good pace.
No, I can not. What I do know is that somehow some PCs have ridiculously slow download speeds, while other ones have 0 problems.
Lets see if you don’t get those updates I am sure you will be happy still and don’t complain.
