Could you COPY one of your tables out to disk via psql, and then COPY it
back into the database, to reproduce this measurement with your real data?
Also, how much is the disk load, and CPU usage?
As long as psql is factor 20 better than your perl script, I think that
the perl interface is what should be optimized.
On a table with no indices, triggers and contstraints, we managed to
COPY about 7-8 megabytes/second with psql over our 100 MBit network, so
here the network was the bottleneck.
You should think about making your perl program writing the COPY
statement as text, and piping it into psql.
HTH,
Markus
