By "second attempt" do you mean you un-retired or reclaimed it?

Completely new Fort, same world. I usually maintain copies of a world, and backups of my saves.

Well... I did the same on my own - played a fort, lost it by having a gobbo siege and opening a circus simultaneously... The game went to 1-2fps on a 3.5GHz Core i5... There were approximately 65 hostile units, including clowns... LOL

After that I've settled a fort right adjacent to the one with clowns to see if they are able to migrate from one part of the world map to the other...

I've noticed the same symptoms you describe here: cave moss grows inside even before any caves were opened, and fps is much lower than in the first fort... I get 180+fps on a fresh embark and less than 100fps on the "second fort" on the same map (NOTE: the same 16x16 tile of the world map), same biome, same river...

Maybe its related with the overpopulation Toady fixed today...I got one world with one billion humans...look at the populations of this world.

Just checked, and there is an abandoned fort very close by, so that might have something to do with it. A fort in another area does not seem to have the same problem, even if I up the size to 7x7 and invite the circus to town (40fps after the clown act starts).

But there is some race with population above 1 million?

Populations according to legends export:
231132 Dwarves
202419 Humans
35382 Elves
235927 Goblins
1945 Kobolds
Total: 706805

Near one million individuals, which seems like quite a lot, but is not close to the astronomical numbers as caused by the population bug Toady the Great fixed.

What is the size of the world? Worlds above small aren't working very well. Toady recommended to not play in them until he does some optimization.

I don't think I messed with the standard settings, so it should be on 'medium'. I'm not sure if that has anything to do with the fort slowing down, though...

The existence of cave moss and the abandoned fort in the same region might be indicative of something spilling over from fort-to-fort. Also, the detail that a new fort in another region, but the same world, does not experience the extreme slowing down, does also indicate it is likely it is somewhat region-based.

Now the events of the world are played in real time. As a medium world has many things happening, it slows downs your fps at fortress mode. This is known. Try to play at small worlds for a while.

This has been quite some time ago, and I think this issue can be 'closed'. I've not seen the same behaviour in the latest version (0.40.24). I abandoned a fort after breaching the cavern, started a new fort right next to it, and didn't see the massive slowdown.

Yeah, there have been a number of performance improvements since then (e.g. 0.40.05). Since this save isn't compatible with recent versions of DF, it would be best for specific performance-related issues to be reported separately.
