Have you tried "vmstat -i"? It might give an indication if any of the device interrupts is causing the problem. I remember a similar problem on FreeBSD machines where the USB interrupt was shared with the NIC interrupt. The USB interrupt handler is quite heavy-weight, so it slowed down the processing of NIC interrupts, even if no actual USB devices were in use at all. Moving the USB controller to a different interrupt (or disabling USB completely) solved the problem. Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co.
