Would updating my iMac to Monterey or Ventura slow it down?

The ONLY TIME I've ever upgraded my OS and got a performance boost was way back when Snow Leopard was released.
I guess newer OS's have more features and therefore run more processes or whatever... How much of a performance hit would I take by upgrading this iMac?

Honestly, I would say no.

I have a similar machine but it has half of the RAM. Still runs great on Ventura with no significant performance impact. I don't run demanding apps on a daily basis though. The only thing noticeable is it takes 20s to launch my 9 autostart apps after login.

A VERY important question:
What kind of drive is in the iMac?

Unless it's an SSD, it might very well slow down.
If it's a platter-based HDD, the answer is almost certainly, "yes" (it will slow down).

In case you’re interested, 11.7.6 was recently released. The updates fixes some kind of exploit.

With an SSD and that much RAM, you ought to be just fine.
