Troubleshooting Virtualization Performance Issues – Virtual Packet Loss

IT professionals often assume application performance will suffer in virtual environments but don’t understand the reasons why. Virtual packet loss could be the culprit.

This five-minute video from Matt Cauthorn, Sr. Field Systems Engineer at ExtraHop Networks, explains virtual packet loss, which is essentially the effects on TCP of resource contention in the hypervisor, resulting in retransmission timeouts (RTOs) and what appears to be terrible network performance. Fixing this problem is easy–just add hypervisor resources or move the VM to another host. But detecting the problem is difficult without advanced TCP analysis. To end the video, Matt gives a quick peek inside the ExtraHop system to show off its advanced TCP analysis capabilities.
