Using a simple global array to be the list of addresses and pointers,
full load time went from about 3ms to 15ms. But it works just fine and
the lookups are so fast the microsecond timer registers zero.

Yes. Of course a single pointer would be 8 bytes when
it is compiled for 64 bits,
but it would not need to be. When your existing route table is an array
rather than a collection of malloc'ed objects linked by pointers, the
"pointer"
from the address lookup table into the route table could be the smaller index
into the route table (that would easily fit in an unsigned short integer, allowing
for 65535 gateways).
Or, in 32 bit mode a simple pointer can be used (4 bytes per entry).
