I don't know the details, but it could be that this person for example
runs an older GNOME version, plus, most likely does not "surf the modern
Btw, I just tried running GNOME on one or our systems and it was quite
easy to get down to 118 MiB. (In this case, I removed non-essential
programs such as Bluetooth support, screensaver etc, plus the actual
Xserver, so that only the GNOME processes was counted.)

XP has been the "standard" VDI OS in the rest of the world as well. The
problem is just that it's obsolete: The ability to buy support (even
"extended") disappeared 1 month ago. I know that some organizations
doesn't care about this, but personally, I would never build up a new
infrastructure based on an obsolete operating system.

Seeing is believing...

Yes, but which applications? The resource requirements are very different.

Please compare apples with apples. ThinLinc is not GNOME, and ThinLinc is
One can argue, though, that some standard Linux desktop consumes more
memory than a similar Windows Terminal Server session. This is probably
true. A minimal WTS session is very lean. But when you start adding
applications, the difference mostly evens out.
If you want to run a Windows desktop instead of Linux one, since this
perhaps scales better with your application mix (or for some other
reason), feel free to do so with ThinLinc. As you probably know, we have
put a lot of effort into making ThinLinc the best platform integration
product. ThinLinc does not restrict you to a certain desktop type or
application server operating system. Being able to mix applications and
platforms is one of the main features with our product.
