Lately df_27_176_38c has been running intolerably slow.

I can't figure it out, but one thing I've changed in my playing habits was to start building tons of bins and stone blocks (trinkets/stone littering the landscape puts me off from the game - despite being a donor since 2-d version).

I tried an older save and that runs 50-75 fps with 58 dwarf population and 7 soil layers exposed. My game runs 9-14 fps and has just 27 dwarves and 2 layers exposed. Generally speaking, the fortress itself is much smaller.

One thing that can DRASTICALLY alter your fps is the pathing routines.  I noticed this when I tried to strip-mine a 2*2 down to the bottom.  At times, when some spots were deeper than others, I could get as few as 15 fps, although I probably averaged overall about 90, with a mode at 100.

So if your dwarves are taking a winding path to get to some stone or wood...

I'll take a look at it at some point.

I had about 30 dwarves when I started excavating an entire mountain. Before I designated anything I was at about 80-90 FPS ( Was a big map ), after designation and subsequent dwarf job pickup I dropped to about 15 until the job was done, at which point it shot back up into the 70-80 range.
