Although technically routers are just a special type of computer, they are quite different to general purpose computers in terms of demands on RAM. The RAM used (assuming everything is working normally) tends to stay very flat for any given set of features and configuration. There's not really anything wrong with a steady state of around 66% RAM used, and it wouldn't improve performance if that was only 33%. As long as you're not getting close to 100%, or seeing huge spikes, there's really no problem to solve; routers are not normally loading and unloading big executables as a constant thing, or suddenly finding a demand for a massive amount of working memory. My GT-AX6000 has 1GB RAM and typically sits about 66% used.
So, the big question is why you think it's a problem? Are you actually (close to) running out of memory at any point? Are you seeing any signs of memory starvation? Is there any problem you are trying to solve (beyond just the number that is reported to you)?
If it's working and performing well, and there's no specific problem, there is absolutely nothing wrong with a router sitting around 66% RAM used.

Just want to reopen this case again. I have a brand new GT-AX6000 Rapture. It is the first time I encountered my router consuming almost 96-97 percent of RAM. When I tried to set the media server and attached the flash drive on the USB port, then this happened. Now, I'm trying to figure out some answer. Would it be fine running on that level of RAM usage for long period of time? I also noticed the low level of CPU usage. It's kinda weird actually. Is it really just a bug on the USB application side?

I really have no answer on this. But I did want to report that I DO have a USB thumb drive plugged in and I am running media, smb, and ftp servers. And my RAM usage has remained as reported above for this entire period.
Yesterday I was looking at a friend's old Asus RT-N12D1 that was doing next to nothing at the time. His single-core CPU was below 10% but his RAM usage was maxed out. That device has only maybe 30M RAM but he had only 5 devices connected and again, they were doing mostly nothing.
Can you enable telnet/ssh, connect with a shell, and run the free command? That will show how much of the used RAM is in cache/buffers. I understand that these can be "reclaimed" if true RAM demand gets high enough.

Ok, so I went to the GUI and enabled ssh. Executed the free command and it reflects what I actually see on the GUI side. Then, I played with the settings. I changed the USB mode from 3.0 to 2.0. There you go, the memory usage went low to 63-64%. Scanned the thumb drive through the health scanner and no bad sectors found. It was clean. Probably the feature 3.0 is the culprit. It consumes too much memory but less on cpu usage. hmmm... still wondering. I want answers, hope ASUS will be able to resolve this.

Interesting! Just to keep the confusion level high, my USB is on the 3.x setting. Cheers!
