Ran Siege benchmark in internet mode with 300 concurrent users and 100 repetitions with a 0-5 second delay. I wrote a logstats.sh bash script which logs top and free -m stats output every 1 second for web1, web2 and web3 servers. The logstats.sh bash script then allows filtering output by cpu and memory stats to figure out peak cpu and memory usage loads.
Click one of the 3 buttons below to view full filtered stats for each web1, web2, web3.
