If you examine the packet it'll say "invalid checksum". This will be because your network card is doing TCP checksum offloading, and you can almost certainly ignore the warning or turn it off. See: http://wiki.wireshark.org/TCP_Checksum_Verification http://www.wireshark.org/docs/wsug_html_chunked/ChAdvChecksums.html > As I said before I really don't know what I am looking at. Use the wireshark throughput graph for a starter. If you don't understand TCP/IP, wireshark probably won't help you much - but then, I learned about TCP/IP with wireshark. Consider doing the same - dive in, read about it, and have a play. I won't be too surprised if the issue turns out to be related to TCP window sizes and window scaling differences between the two machines. -- Craig Ringer Tech-related writing: http://soapyfrogs.blogspot.com/ -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
