Mine really aren't bad at all as I have a 3080. Most renders are done with 5000 iterations at about 20 minutes, and I can run them overnight while I'm sleeping. This means pretty much anything I'm able to stage during the day is able to be rendered at night. My bottleneck isn't so much time as it is VRAM. My 3080 has 10 gb of VRAM, but if the number of assets in a scene exceed that, then the entire job gets dumped to the CPU. That's my bottleneck; I have to keep the scenes under 10 gb of assets (hair and fur are the biggest issues). But that only happens rarely and I've developed a few workarounds to solve it.
