Well, OSDL has run tests on PostgreSQL as recently as 20050908 but the host with the results isn't responding to me, so no idea what the tests were. Also, they use various tests involving PostgreSQL to test the scalability of the Linux kernel, so you can see how postgres runs with various different kernel patches. http://www.osdl.org/lab_activities/kernel_testing/stp/search.lnk/search_test_requests Enter "postgresql" in the software field, or select one of the pgsql tests. Maybe someone else will have more luck than me getting the results... Have a nice day, -- Martijn van Oosterhout <kleptog@xxxxxxxxx> http://svana.org/kleptog/ > Patent. n.
