It may use a lot of RAM, but as said:
RAM exists for a reason: if your computer can store lots of stuff in its short-term memory, then it can recall those things quickly later on. And if your computer doesn’t end up needing that stuff, it will toss it away to make room for other programs that need those resources.
So, by that logic, having your RAM almost full can be a good thing. It becomes a bad thing when your RAM is constantly full and slowing down your system. If what you’re doing needs more RAM than your computer has to offer, it’ll start swapping some of that short-term memory to your computer’s hard drive, which is much slower.
HTG Explains: Why It’s Good That Your Computer’s RAM Is Full
In a nutshell: Don’t flip out just because Chrome is using lots of RAM. That means its doing its job. If it’s taking up so much RAM that things are noticeably slowing down, however, you do indeed have a problem.
Do you not want to use the full capability of your available RAM?
I find it strange, I really do...that ever since I started using Chrome, I've always found it so much faster, smoother, more reliable than any I.E version and yet others find I.E better. I can have 20 tabs open in Chrome (Like I have right now!) and never any issues, with I.E11 It struggles with 3! I always find that my PC's fan speed jumps up a lot whenever I try to open more tabs on I.E11 too, whereas on Chrome it's always pretty constant.
EDIT: This is all on a desktop PC with 8GB of RAM, WIN7 btw.
Regards experiment...I did one too. Side by side, quite an obvious difference.
PS: The sound thing was an error on my part, or rather filezilla's! Now corrected.
