Visual Studio Community complete download?

Hi All, I am currently in the process of deploying a visual studio community install to a number of machines on our network but seem to be running into a brick wall with components. I have create a layout on a server using (server&path)vs_community.exe --layout e:\vslayout --all --includeOptional --includeRecommended

expecting this to download the full and complete install which would be roughly 250gb or round about there in size.

the download ends up being 55gb which can be explained by compressed files but still expected this to be much larger.

when I install to the clients I'm using (server)vs_community.exe --all --passive wanting this to install absolutely everything available, now this installs but when opening the installer on the client again, clicking modify, it is showing that it wants to install another 113gb, then after this another 20gb and so on and so on. I have tried using vs_community.exe --all --passive --includeOptional --includeRecommened --noWeb but this has the same result.

how can I download a full and complete layout that has absolutely everything, all bells and whistle's or even if this is possible? reason behind this is not because of a lack of internet for the client machines, just wanting to be able to fully load a machine with everything that our users can and do use without having to download the extra components when the users are wanting to use them and are not installed on the machines, and the fact that a network install for us is faster than a internet install as we use fibre channels between cabinets in the various buildings we use, plus this will also alleviate using internet bandwidth for other users on the network(s)

can anyone be as kind to help / answer this please many thanks steve
