We've rolled out a new website. Previous server had older website. The new website has had performance issues, slowness etc. Although it seems this is an issue with the new code I want to rule out any other possible issues.
Current Internet line is 100 down / 11 up. The Webserver is connected directly to a Sonicwall NSA 3500 on a 1000 Mbps full-duplex link.
The Webserver is a physical server - ProLiant DL380p Gen8. 2 Xeon E5-2640 @ 2.5 GHz, 32 GB RAM, Smart Array P420i, Windows 2008 Std., 2 1GB network cards teamed, 2 other unused.
Webserver is Apache.
I need to prove the server and connection it not the issue. What is the best way to do that.
