What are some 5-10 y/o wads that really push vanilla/boom?

Ribbiks' swim with the whales gets about 18fps anywhere on the first map on mbf on a pentium 166. Runs great on a p3-700 underclocked to 233, unless I up the resolution to 640*480, where it will sink to the low 20's. Eternal is the wad that most pushes vanilla and these older machines, I'm guessing? For boom ones I guess I'm going to have to stay away from anything made in the last 10 years or so.

EDIT: not really looking for something with 9,999 monsters, more architecture and map size and source port features and such.

Frozen Time (Boom, though original Boom or MBF would not run it)

Would Memorial count?

If that counts, then I guess object 34 sonar counts too.

I remember when Vrack 2 dropped, I had trouble running it in double-figure framerates on the Cyrix 200MHz I had at the time. I've always had a shit computer though.
