If you use INSERT, you'll incur a network round-trip delay for each record. Try using COPY FROM instead, possibly to a temporary table if you need more complex calculations. If you do this, there won't be a huge difference between local and remote access as long as the bandwidth is sufficient. -- Florian Weimer <fweimer@xxxxxx> BFK edv-consulting GmbH http://www.bfk.de/ Durlacher Allee 47 tel: +49-721-96201-1 D-76131 Karlsruhe fax: +49-721-96201-99
