One problem with any chip which requires alligned data is that
performance suffers when addressing bytes, to the point that a program
may become impractical. One of the people here checked his Sun-30
(68020) against his Sun-4 (SPARC). The three ran troff about 5x faster.
This doesn't mean RISC is bad in a workstation, but it can have
performance problems in software we take for granted.
A question: has anyone benchmarked nroff/troff on the VAXstation 3100
(VAX) and DECstation 3100 (MIPS)? Would some of the MIPS readers like to
comment on performance in this area vs. 68020 or 80386?
