I was thinking of the NIC, thats why I tried it on localhost (bypassing the NIC(?)). I'm using a re-nick: re0: port 0x7e00-0x7eff mem 0xfd3ff000-0xfd3fffff irq 18 at device 0.0 on pci3 I have not changed anything, except upgrading the world + kernel. No hardware was added, no bios-settings where changed. The only thing I can think of is that I might have changed a sysctl a long time ago that boosted my performance, and that change have been lost after the reboot. -- Ståle Kristoffersen staalebk@ifi.uio.no
