AIM

To build the testing Framework.

Reference Material

Paper_16-Performance_Evaluation_of_Private_Clouds.pdf

http://www.junauza.com/2012/05/best-system-benchmarking-tools-for.html

Software

Install following software:


# apt-get install -y  libx11-dev libgl1-mesa-dev libxext-dev perl perl-modules make gcc nfs-common
postgresql-9.1 postgresql-contrib-9.1 mbw iperf

CPU

The following software are introduced for testing CPU Performance:

Linpack
Lookbusy

Linpack

Note: Only works on INTEL CPU.

Linux

Windows

Mac

Linux Steps:

$ tar xvf l_lpk_p_10.3.4.007.tgz
$ cd linpack_10.3.4/benchmarks/linpack
$ ./runme_xeon64

You can see the testing result via tail -f lin_xeon64.txt.

Note your CPU’s temperature and your system load are changing.

Lookbusy

https://www.devin.com/lookbusy/
Download and install it via:

# wget https://www.devin.com/lookbusy/download/lookbusy-1.4.tar.gz
# tar xzvf lookbusy-1.4.tar.gz
# cd lookbusy-1.4/
# ./configure --prefix=/usr
# make && make install
# lookbusy

Default will add 50% load to each CPU.

Memory

Stream

https://www.cs.virginia.edu/stream/ref.html

Get the source code from: https://www.cs.virginia.edu/stream/FTP/Code/

Then compile it and run:

# make stream_c.exe
# ./stream_c.exe

Disk IO

Bonnie++

测试工具Bonnie++的使用

Network IO

Iperf

To be added.

OverAll

System Level Testing Framework.

UnixBench

Download the source file, then run it, and see the result.

# wget http://byte-unixbench.googlecode.com/files/UnixBench5.1.3.tgz
# tar xvf UnixBench5.1.3.tgz
# cd UnixBench
# make
# ./Run 2>&1 | tee RunResult.txt

USB Ethernet

Insert the USB Ethernet Dongle into the Ubuntu14.04, it will be automatically recognized and initialized.

$ dmesg | tail 
    [10323.307662] asix 2-2.2:1.0 eth1: register 'asix' at usb-0000:00:1d.7-2.2, ASIX
    AX88772B USB 2.0 Ethernet, 84:xx:xx:xx:xx
    [10323.307704] usbcore: registered new interface driver asix
    [10324.285425] IPv6: ADDRCONF(NETDEV_UP): eth1: link is not ready
$ ifconfig eth1
    eth1      Link encap:Ethernet  HWaddr 84:xx:xx:xx:

Be care to see the udev rules definition:

$ cat /etc/udev/rules.d/70-persistent-net.rules 

# USB device 0x:0x (asix)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="84:xx:xx:xx:xx",
ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

IP Configuration

Add the following items into the network configuration file:

# vim /etc/network/interfaces 
    # usb network eth1
    allow-hotplug eth1
    iface eth1 inet static
    address 10.0.80.1
    netmask 255.255.255.0

Now restart the network, to see the ethernet has been enabled.

DHCPD Configuration

Add following configuration to the /etc/dhcp/dhcpd.conf:

### this is for USB NET

subnet
10.0.80.0 netmask 255.255.255.0 {
# --- default gateway
option routers
10.0.80.1;
# --- Netmask
option subnet-mask
255.255.255.0;
# --- Broadcast Address
option broadcast-address
10.0.80.255;
# --- Domain name servers, tells the clients which DNS servers to use.
option domain-name-servers
223.5.5.5,180.76.76.76;
option time-offset 0;
range 10.0.80.3 10.0.80.13;
default-lease-time 1209600;
max-lease-time 1814400;
}

IPtables and dhcpd

Add following items into the ~/.config/awesome/rc.lua

autorunApps =
{
--.........
"blueman-manager",
"fcitx",
"/home/dash/Downloads/what/whatpulse",
-- "pidgin",
"sudo iptables -t nat -A POSTROUTING -s 10.0.70.0/24 ! -d 10.0.70.0/24  -j MASQUERADE",
"sudo iptables -t nat -A POSTROUTING -s 10.0.80.0/24 ! -d 10.0.80.0/24 -j MASQUERADE" 
"sudo dhcpd wlan0 eth1",

Now everytime we reboot the system, it will automatically start the dhcpd server and let OpenWRT as the access Point.

Kernel IPV4 Forwarding

Check the configuration:

# sysctl -a | grep forward

Enable the forwarding manually:

# sysctl net.ipv4.ip_forward=1

added it into system startup:

# vim /etc/sysctl.d/30-ipforward.conf
net.ipv4.ip_forward=1
net.ipv6.conf.default.forwarding=1
net.ipv6.conf.all.forwarding=1
