There is a set -of configuration changes that, when applied together, will increase the ability -of Linux to transmit and receive data. The following enhancements were -originally acquired from settings published at https://www.spec.org/web99/ for -various submitted results using Linux. - -NOTE: - These changes are only suggestions, and serve as a starting point for - tuning your network performance. - -The changes are made in three major ways, listed in order of greatest effect: - -- Use ip link to modify the mtu (maximum transmission unit) and the txqueuelen - parameter. -- Use sysctl to modify /proc parameters (essentially kernel tuning) -- Use setpci to modify the MMRBC field in PCI-X configuration space to increase - transmit burst lengths on the bus. - -NOTE: - setpci modifies the adapter's configuration registers to allow it to read - up to 4k bytes at a time (for transmits). However, for some systems the - behavior after modifying this register may be undefined (possibly errors of - some kind). A power-cycle, hard reset or explicitly setting the e6 register - back to 22 (setpci -d 8086:1a48 e6.b=22) may be required to get back to a - stable configuration. - -- COPY these lines and paste them into ixgb_perf.sh: - -:: - - #!/bin/bash - echo "configuring network performance , edit this file to change the interface - or device ID of 10GbE card" - # set mmrbc to 4k reads, modify only Intel 10GbE device IDs - # replace 1a48 with appropriate 10GbE device's ID installed on the system, - # if needed. - setpci -d 8086:1a48 e6.b=2e - # set the MTU (max transmission unit) - it requires your switch and clients - # to change as well. - # set the txqueuelen - # your ixgb adapter should be loaded as eth1 for this to work, change if needed - ip li set dev eth1 mtu 9000 txqueuelen 1000 up - # call the sysctl utility to modify /proc/sys entries - sysctl -p ./sysctl_ixgb.conf - -- COPY these lines and paste them into sysctl_ixgb.conf: - -:: - - # some of the defaults may be different for your kernel - # call this file with sysctl -p <this file> - # these are just suggested values that worked well to increase throughput in - # several network benchmark tests, your mileage may vary - - ### IPV4 specific settings - # turn TCP timestamp support off, default 1, reduces CPU use - net.ipv4.tcp_timestamps = 0 - # turn SACK support off, default on - # on systems with a VERY fast bus -> memory interface this is the big gainer - net.ipv4.tcp_sack = 0 - # set min/default/max TCP read buffer, default 4096 87380 174760 - net.ipv4.tcp_rmem = 10000000 10000000 10000000 - # set min/pressure/max TCP write buffer, default 4096 16384 131072 - net.ipv4.tcp_wmem = 10000000 10000000 10000000 - # set min/pressure/max TCP buffer space, default 31744 32256 32768 - net.ipv4.tcp_mem = 10000000 10000000 10000000 - - ### CORE settings (mostly for socket and UDP effect) - # set maximum receive socket buffer size, default 131071 - net.core.rmem_max = 524287 - # set maximum send socket buffer size, default 131071 - net.core.wmem_max = 524287 - # set default receive socket buffer size, default 65535 - net.core.rmem_default = 524287 - # set default send socket buffer size, default 65535 - net.core.wmem_default = 524287 - # set maximum amount of option memory buffers, default 10240 - net.core.optmem_max = 524287 - # set number of unprocessed input packets before kernel starts dropping them; default 300 - net.core.netdev_max_backlog = 300000 - -Edit the ixgb_perf.sh script if necessary to change eth1 to whatever interface -your ixgb driver is using and/or replace '1a48' with appropriate 10GbE device's -ID installed on the system. - -NOTE: - Unless these scripts are added to the boot process, these changes will - only last only until the next system reboot. - - -Resolving Slow UDP Traffic --------------------------- -If your server does not seem to be able to receive UDP traffic as fast as it -can receive TCP traffic, it could be because Linux, by default, does not set -the network stack buffers as large as they need to be to support high UDP -transfer rates. One way to alleviate this problem is to allow more memory to -be used by the IP stack to store incoming data. - -For instance, use the commands:: - - sysctl -w net.core.rmem_max=262143 - -and:: - - sysctl -w net.core.rmem_default=262143 - -to increase the read buffer memory max and default to 262143 (256k - 1) from -defaults of max=131071 (128k - 1) and default=65535 (64k - 1). These variables -will increase the amount of memory used by the network stack for receives, and -can be increased significantly more if necessary for your application. - - -Additional Configurations -========================= - -Configuring the Driver on Different Distributions -------------------------------------------------- -Configuring a network driver to load properly when the system is started is -distribution dependent. Typically, the configuration process involves adding -an alias line to /etc/modprobe.conf as well as editing other system startup -scripts and/or configuration files. Many popular Linux distributions ship -with tools to make these changes for you. To learn the proper way to -configure a network device for your system, refer to your distribution -documentation. If during this process you are asked for the driver or module -name, the name for the Linux Base Driver for the Intel 10GbE Family of -Adapters is ixgb. - -Viewing Link Messages ---------------------- -Link messages will not be displayed to the console if the distribution is -restricting system messages. In order to see network driver link messages on -your console, set dmesg to eight by entering the following:: - - dmesg -n 8 - -NOTE: This setting is not saved across reboots. - -Jumbo Frames ------------- -The driver supports Jumbo Frames for all adapte |
