Following up on recent discussions about excessive SSD writes, my experience is that the write volume is directly related to the amount of swap space in use, which for my usage is largely driven by Safari memory usage. I need at least 25 tabs open for my work, and some of these (Atlassian Confluence) use well-over 1GB.

What I have seen, which surprised me, was that Safari appears to cache pages (as "Safari Web Content" processes) even after the tab has been closed.

Is there any way to prevent this behaviour? There used to be caching controls in the Safari Developer menu, but these appear to have been removed.

I'm starting to experiment with Edge, which has extensions for suspending tabs, which suits my workflow. It gives the impression of not being quite a snappy as Safari, but is quite acceptable otherwise.

I hate that I have to change my way of working to keep the machine happy, rather than vice versa!

Unless and if Apple pushes a solution/fix, you have found the solution.

The cache is kept so that if you return to a recently visited site it opens immediately.
The cached memory gets released as soon as the operating system needs RAM. As a user you don't need to be concerned with it.
