Aaron, Thanks for your reply. Here is some output from some dd's on the disk that I'm reading/writing to. > dd if=/dev/zero of=testfile count=1000000;dd if=testfile of=/dev/null 1000000+0 records in 1000000+0 records out 512000000 bytes transferred in 27.951769 secs (18317267 bytes/sec) 1000000+0 records in 1000000+0 records out 512000000 bytes transferred in 16.864945 secs (30358830 bytes/sec) > dd if=/dev/zero of=testfile count=1000000 ; dd if=testfile of=/dev/null 1000000+0 records in 1000000+0 records out 512000000 bytes transferred in 28.492921 secs (17969376 bytes/sec) 1000000+0 records in 1000000+0 records out 512000000 bytes transferred in 16.605797 secs (30832607 bytes/sec) Am I reading right, the max network transfer rate from this disk will be between 143Mbit and 246Mbit/sec? Is there a way to determine if there is an IRQ conflict? How do you find out what IRQ's are currently used by the system?
