sonata31380 Posted August 21, 2011 Share Posted August 21, 2011 I have a network card Intel ® PRO/1000 gigabit and the network performance seems very low. How can I check it precisely? Quote Link to comment

sonata31380 Posted August 21, 2011 Author Share Posted August 21, 2011 I specify that the server unRAID and PC are connected to a Gigabit switch. Quote Link to comment
monza Posted August 21, 2011 Share Posted August 21, 2011 What speed are you getting? How big is the test file you are using? Is the transfer over SMB? Do you have another PC on the network..what speed do you get transferring between those two machines (take the unRaid out if the equation for the testing...) Quote Link to comment

dgaschk Posted August 21, 2011 Share Posted August 21, 2011 The server is connecting at 1000MBPS. Is the client? Quote Link to comment
cyrnel Posted August 21, 2011 Share Posted August 21, 2011 See all the link up/down messages? Your nic is definitely not happy. There was also an unhandled interrupt or something causing the nobody cared trace at 13:19. That's either your nic or something that shares IRQ 17 with it. Can we see the output from: cat /proc/interrupts This doesn't look like a physical link problem but a simple test to get out of the way would be to try another Ethernet cable and another port on the switch/router it's plugged into. What motherboard is this? Quote Link to comment

sonata31380 Posted August 22, 2011 Author Share Posted August 22, 2011 I rebooted the server with the option irqpool as shown in syslog and I went to over 35 Mb/s Quote Link to comment

mbryanr Posted August 22, 2011 Share Posted August 22, 2011 I found a mention of this in a kernel bug https://bugzilla.redhat.com/show_bug.cgi?id=457648 Quote Link to comment
sonata31380 Posted August 22, 2011 Author Share Posted August 22, 2011 I just saw indeed the problem but how to fix it with unRAID? Quote Link to comment
mbryanr Posted August 22, 2011 Share Posted August 22, 2011 As a work-around, it may require to change bios settings, or potentially adding a line to one of the .conf files First it will require to identify which bios option is causing the irq nobody cared fault... Recent info on the bug https://bugzilla.redhat.com/show_bug.cgi?id=713351 Appears to be a problem with the Asus MB https://bugzilla.kernel.org/show_bug.cgi?id=39122#c3 http://vip.asus.com/forum/view.aspx?board_id=1&model=E35M1-M+PRO&id=20110507053520320&page=1&SLanguage=en-us Quote Link to comment

mbryanr Posted August 22, 2011 Share Posted August 22, 2011 yes. Don't know much more than that as a quick search reveals many reports of this irq error and the Asus SandyBridge MB http://www.mentby.com/chris-palmer-2/ http://forums.vr-zone.com/hardware-depot/1437078-asus-p8h67-v-intel-gt-1000pro-nic-fedora-14-getting-very-slow-network-speeds.html http://forums.overclockers.co.uk/showthread.php?t=18285181 and more.

sonata31380 Posted August 23, 2011 Author Share Posted August 23, 2011 For nearly 14 hours I rebooted the server without the error appears. Quote Link to comment
cyrnel Posted August 23, 2011 Share Posted August 23, 2011 Getting back to the OP, how's the net performance, both reading and writing? If you get a chance, try pci=nomsi instead of the noacpi. It completely depends on how the configuration is settling out but one or the other may be faster. Quote Link to comment
sonata31380 Posted August 23, 2011 Author Share Posted August 23, 2011 With acpi=off reading and writing : 25-30 Mb/s With pci=nomsi errors appear Quote Link to comment
