I can't believe these figures.

I can't reproduce the complaint using a 64MB PII-266 running -CURRENT -
there's no evidence of lack of speed, and profiling file(1) doesn't
show any anomolies.

It is somewhat slower on my 8MB 386, but not unreasonably so:
pc0640% time file src/Z/dhcp-2.0b1pl26.tar.gz 
src/Z/dhcp-2.0b1pl26.tar.gz: gzip compressed data, deflated, last modified: Thu 
Jan  1 10:00:00 1970, os: Unix
file src/Z/dhcp-2.0b1pl26.tar.gz  1.96s user 0.83s system 98% cpu 2.823 total
pc0640% 

Note that this is somewhat more than twice the time Leif claimed for
his P-60 - and a P-60 should be more than twice the speed of a
386SX-25.

Unfortunately, I can't profile it on my 386: It's running 2.x and I
deleted the profiling libraries due to lack of space.  It will happily
run the profiled ELF file(1), but doesn't generate any timing data.

Looking at ktrace with MALLOC_OPTIONS=U, it does do a lot of
realloc()ing (once for every 20 active lines in .../magic) and sbrk()s
to a maximum size of ~390KB - not really significant.

All I can think of is that Leif has a problem with his P-60 system.
