Caching or not caching, previous releases utilised 10-20% less (which is a lot). That's it.
If I may as this thread continuous to be derailed: I merely said that this (1903) release utilises more RAM that previous ones.
(How much RAM does one have fitted, how much of it is utilised normally and during peak times by OS, and whether this or that particular ratio is a good or bad thing, has nothing to do with my comment and is a bit academic (and very moot) point here)
I have 24 GB RAM and I don't worry about how much or how little of that my computer uses. I made sure I have enough to edit the occasional photo.
I don't get upset because someone makes a statement; that would be counter productive. As Keith said, " It's not doing any good if it's just sitting there unused." IOW, it's there to be used when I need it.
Hi there
@CountMike
That's what's paging is for (and swapping) -- so you can run more applications than would you would be able to use concurrently if these applications "ate up all the RAM". Obviously paging within reason otherwise you get a condition known as "thrashing" -- when there's actually too little RAM so each application has to keep continuously accessing the paging file.
While people might be "obsessed" for curiosity reasons how much RAM / How little is used the OS's task manager makes the best available use of RAM by only allocating that amount of RAM that's actually required by running applications and it does this dynamically ("Demand paging").
Once you have an adequate amount adding more RAM does not improve performance in any significant way - even if you disable paging (you shouldn't do that anyway) -- the OS will then still allocate paging etc in any case if it needs to.
These days almost the best thing you can do to improve computer performance is to get the fastest possible disks (and a Mobo bus that supports fast I/O) Nice SAS systems would be good but a bit overkill for domestic computers.
Obviously other components like graphics and CPU need to be considered -- however this depends entirely on what you use the computer for -- you don't need an i7 QUAD type processor for basic file serving, NAS type backups, multi-media streaming, e-mail, torrent downloading, general office type stuff and stock trading etc.
