Preparing performance test

While preparing for a performance test at a high school, I found that after a certain amount of requests to the webserver, there was a timeout of 3 seconds for the following requests. Very strange. That could mean that there’s a smart firewall delaying requests after a receiving too many requests from one ip.

I will install some firefox addons to check host and guest ips:

• showip to show ip of visiting website
• externalip to show your current external ip

Diagnostics performed:

• ethtool eth0 to check the NIC status
• traceroute -I address (-I to send ICMP requests)
• nslookup address
• digg address
