Global WAN(G-WAN) is a web server developed by Pierre Gauthier.
It is written in C and is one of the fastest static web server I’ve ever tested with Apache Bench.

# create the download and build directory
mkdir -p ~/build/gwan
cd ~/build/gwan

sudo apt-get install -y sqlite3 libtokyocabinet-dbg libtokyocabinet-dev tokyocabinet-bin gobjc++
# install Go language
sudo apt-get install -y golang
# link go lang binary
sudo mkdir -p  /usr/local/go/bin/
sudo ln -s /usr/bin/go /usr/local/go/bin/go

# download gwan binaries
wget http://gwan.com/archives/gwan_linux64-bit.tar.bz2
tar -xjf gwan_linux64-bit.tar.bz2
cd gwan_linux64-bit

sudo JAVA_HOME=/usr/lib/jvm/java-7-oracle ./gwan

Set Java Environment


# example 1.
sudo sh -c 'echo "JAVA_HOME=\"/usr/lib/jvm/java-7-oracle\"" >> /etc/environment'

# example 2. Setting JAVA_HOME and PATH for a single user
vi ~/.bash_profile
export JAVA_HOME=/usr/lib/jvm/java-7-oracle
export PATH=$PATH:$JAVA_HOME/bin

# example 3. Setting JAVA_HOME and PATH for all users
vi /etc/profile

export JAVA_HOME=/opt/jdkx.x.x_xx
export PATH=$PATH:$JAVA_HOME/bin

Simple Apache Bench Test
