The compacted macros have been entirely removed from DWB 2.0.
(They never worked quite right.)  But if it's any help, 
both DWB 2.0 Nroff and Troff are TWICE AS FAST as the ones in DWB 1.0!
Most all tables, especially macro lookup tables are now hash coded. 
Our benchmarks show a performance improvement of a factor of 2 across
the board on all machines (from PCs to mainframes).  A big help
to those troff-hogged CPUs.
