Discovery of the HFS area, before any of the super fun items spawned has caused my frame rate to go from 8-11 to 4 fps.

AKA from Incredibly laggy to ridiculous insanity laggy.

Backed up the save game.

Likely a dozen or so (currently invisible) demons pathfinding like mad.

Possibly.  I hit the bottom floor of the HFS so there is no path to the stuff above it..     Also of note I did not discover a tile of adimantium before hitting it so I received the praise the miners popup and about 10 discovered XYZ messages.

Best way to breach HFS is to mine into the side of one of the pools (water, but magma will work) so that the demons have to "jump" down to get into your fort.  Then you wall it up.  The demons won't jump and then when you wall it up you know where you can and can't dig and nothing got out.

Uhh As you might have noticed if you read the origional post, I did not know the HFS was there, just happened to breech it.

Still no demons though, and the lag is still unbearable.

Well the demons are there.  They're just invisible.

Its a known issue that the Hellspawn when thier pathfinding is blocked cause high level of frame lose. This is jsut the nature of dwarf fortress in the way it calculates path finding every graphical frame refresh.

Three choices, none good:
Abandon fortress for safer grounds.
Knock a hole into the full pits and face the wrath of dwarf slaughter inc.
Upgrade your computer (note even high end computer have problems with dwarf fortress and alot of pathfinding errors).

Fourth choice:  Collapse the ceilings of each z-level on top of the Demons.  The first collapse should kill them ALL

I know.  I'm just stating my experience with a breach.

In my experience, it's cleaner to undermine and collapse a level below the pits.  But to each their own.

Hmm maybe I will just let them kill dwarves... i was really tiring of their incessant whining anyhow... 

Helps framrates in 2 ways... less HFS, less dwarfs.. but, still bug is a bug and was just reporting it.

Just a further note.

It was the invisible demons inside the HFS,  18 toad demons, 1 regular demon, 3 dead military dwarves and 1 civilian death later I now have 14fps.  Dont know why it is above my original FPS speed.
