If I had problem processing 2000 records (or 60 kilobytes) on a
machine less than 20 years old, I would definitely rethink my
strategy/algorithm.

I understand you need to run this under base system (because you want
no ports). I guess you need to do "man awk" - it seems to be the only
language capable enough in such environment. Albeit if you are
masochist, you can stay with csh or learn sh (and sort, cut and few
other things).
