Thank you for the insight. I'm not seeing it but some posters are reporting it and saying its a reason to go to 16GB. I do not agree with this.
It's not uncommon for folks to misattribute the cause of some behavior.
If someone has an 8GB machine and is experiencing website stuttering, I'd like to see the memory tab from Activity Monitor. If it's not displaying red, then the 8GB is not the cause. I'd also like to see the URL and know which browser is in use.
