# Times to ping
$ ab -n 1000 -c 5 http://www.shamun.be

# Keep Alive
$ ab -k -n 1000 -c 5 http://www.shamun.be

# Save to CSV
$ ab -k -n 50000 -c 2 -e apache2r1.cvs http://202.54.200.1/snkpage.html

Where,

• -n 1000: ab will send 1000 number of requests to server 202.54.200.1 in order to perform for the benchmarking session
• -c 5 : 5 is concurrency number i.e. ab will send 5 number of multiple requests to perform at a time to server 202.54.200.1
