21% memory ram usage (1,7GB) in idle Windows 10, help for optimizing

Greetings people I was wondering if you consider as normal or an excess of RAM usage by the system to be using 1.7GB of RAM in idle with 21%.

The very least I have seen is 20% but occasionally I could see a maximum of 30% which equals 2.4GB of RAM.
I'm using Win10 64bits.

I added 12 pictures in the next link so you can see either Task manager or Resource monitor, so then would appreciate a lot if there is something additional I could do for optimizing as much as humanly possible the memory RAM usage since I can imagine everything loads faster when required for working. Just being a little enthusiast. Thanks by the way for all your info.

Idle memory usage isn't a very interesting metric. It's like if a tree falls in a forest and no one is around - if Windows is using 100% of your memory when you're not using the machine, does it really matter?

The way you load things faster is to keep as much in memory as possible because loading things from your hard drive is thousands of times slower than loading something that's already in memory. Windows does this to some degree by caching disk contents in memory (SuperFetch, file caching). As long as some application isn't hogging all the memory at idle, there will be sufficient space for the disk cache to help speed up future application loads.

So don't worry about idle memory usage. You should look at application memory usage when you're actually using the machine - what really matters is that you're not excessively swapping to disk (Resource Monitor->Memory->Processes->Hard Faults/sec) or actually running out of memory (resulting in a crash).

Edit: Just to address your specific question - your idle usage looks fine and I don't see any reason to "optimize" it further.

Your explained answer is well appreciated good sir.

21% memory usage on a system with 8 GB RAM is very reasonable.

Memory usage in any modern OS is highly dynamic. The system memory manager maintains full control over this, always with the goal of maximizing overall system performance. When available memory is plentiful, as is the case in all of the screenshots, applications are permitted to use pretty much whatever memory they want. And why not? Memory is not some precious resource to be used as sparingly as possible. It is the fastest storage in a modern computer and the memory manager always tries to make maximum use of it. Far better that memory be used for something, even if it is only of trivial value, than letting it sit idle. This maximizes performance. Computers with 8 GB RAM perform better than those with 1 GB. But there are limits.

But that is only half the story. If a large application is started the memory usage of currently running processes will be automatically trimmed back to meet the demand. The previously lavish usage comes to an end and they are put on a tight memory budget. Performance will suffer but that is what must be done when resources are limited. Modern operating systems have sophisticated methods of doing this in the most efficient way. And they are continually being refined. But with 8 GB of RAM that probably won't be required very often.

Using memory more efficiently doesn't necessarily mean using less. It means using it more intelligently. That is hard. Many people have tried to "optimize" memory usage in a system they don't understand and the results are predictable - a system that performs worse than before they started.

All the above. Just keep in mind that at times Windows will use as much RAM as is available when running programs, 1 to 100. It's only when there is no more free RAM [or as needed] that Windows will swap some older things out to the Virtual Memory/paging file [older version was the swap file] and performance will suffer a bit. If that happens a lot maybe more RAM is needed on the motherboard. I first saw that back in '92 with WordPerfect 5.1 for Windows on MS-DOS 5 running Windows 3.1 on an 80386/40MHz computer with 4MB RAM, usually got a message about it at about 8 pages of text, did slow down the work, first upgrade was to 8MB.

Hehe thanks for your answer. I can remember just a little bit from that times, the first computer my dad can't remember if was 64MB or 256MB, it was a hell trying to load any program in Win95/98.

By the way, I have seen a couple of times this advice with the virtual memory. Would you recommend it? Which is his advantage and/or disadvantage? This has been called to improve the memory performance.

Haven't looked lately but the written recommendation in Windows Help back in Win7 was for 1.5 times the physical RAM for the Virtual Memory. It may not be necessary if having 16GB or more RAM but it may not be Windows that wants it but some program installations look for something to be there. I use to set it as a max and min figure the same and it didn't fragment on the HDD, the clusters stayed adjacent.

I actually do have this being set automatically. Is there anything would you recommend me to change?

That should be fine, it's what I have.
