Safari Web Content (cached) - using memory

[Martynas]

Hello,

something wrong going with Safari. I open Activity monitor and see a lot of "Safari Web Content (cached)" processes. They take my RAM space even though I have just one tab opened. What is this process and how can I eliminate it? I did not see anything similar earlier (using Mac since 2015)

Edit: All history and cache deleted, no extensions

They will automatically be closed when the ram will be needed by other apps.

The thing is, I have Macbook Air 2018 and Macbook Pro 2017, both which are loaded with lot of information and none of it shows "Cached" safari activity even if there are 10 tabs opened. My iMac Pro, otherwise is clean and freshly reinstalled and still showing "cached" Saafri pages thus using memory

Your iMac Pro has got more free memory to use for cache and friends. Like I said before, they will be removed when the ram is actually needed by other processes.

If anyone still sees this thread - The problem is that these "safari web content (cached)" slows down your computer after a while! Over the years, this has seemed to get worse and worse! Now it is a problem on all of our macs! It does it on all of them - with each OS update it seems to get worse! It never used to happen about 5 or 6 OS versions ago! To have to keep going into the activity monitor and force quit them all the time is a real pain in the ass! Why is Apple doing this??!!!

it used to be way worse before (before mavericks 10.9). The system would have tons of "inactive memory" but would start swapping to the disk. You can hear the disk thrashing constantly and the system would slow to a crawl - even with gigabytes of inactive RAM.

of course the apple advocates at the time defended apple and gave the usual "free ram is wasted ram" lecture. It was a nasty bug that was finally fixed in mavericks.

Well it certainly does not seem fixed - quite the contrary - for us it got worse with mojave update and even worse with catalina update! On all of our computers!

what is your memory pressure and swap used value in activity monitor? If it's green and less than 2 gb, you should be ok. Here's what mine looks like. even though it says 10 gb used with barely an apps open, that's still fine. These things tend to use RAM when it's available and release it when it starts running slow (<10.9 did do this much and would go straight to swap)

Catalina is a joke. Eats my RAM like no tomorrow.
