In addition, NMCI is upgrading existing servers with Bluecoat proxy servers, which provides better capacity and traffic management functions. According to NMCI's own data, a few users account for the majority of NMCI's bandwidth usage, mostly attributed to streaming internet radio and video. New servers will allow bandwidth usage monitoring, down to a command or user level. The security upgrades have been well received by the Navy. On 31 March 2009, Rear Admiral (Ret.) John A. Gauss, Acquisition Director for the NGEN System Program Office (SPO) said during a press conference that "NMCI is the most secure network within the Navy." The Navy and HP measure end-user satisfaction through a series of quarterly satisfaction surveys. End user satisfaction has steadily improved, reaching a high of nearly 86% in February 2008, as compared to 80% in December 2006. This is largely due to the upgrade of nearly 112,000 desktop and laptop computers in 2007, and a combination of network enhancements that are improving speed and reliability. HP is on track to upgrade another 120,000 seats in 2008 at Navy and Marine Corps bases in the US and Asia. Working in tandem with the technology refresh are the virtualization efforts on the network. NMCI is on track to move from 2,700 servers down to roughly 300. The efforts are expected to save more than $1.6 million per year in electricity costs. Additionally, the decrease in the number of servers being refreshed will lower the cost of updating the equipment, leading to a potential savings of at least $1.5 million over four years. A highlight of the Navy's virtualization efforts was its win of InfoWorld's 2009 Green 15 Award, which honors 15 companies and/or organizations for their green IT projects. Ted Samson, Senior Analyst for InfoWorld said of the honorees, "This year's Green 15 winners demonstrate, once again, that green IT projects can be a win-win proposition. These organizations have not only helped the planet by reducing greenhouse gas emissions, preserving trees, and keeping e-waste out of landfills. They've also reaped measurable business benefits, such as significantly lower electricity bills, fewer hardware refreshes, and postponed datacenter-expansion projects – along with gains in efficiency and productivity." In 2006, the NMCI program office was criticized for its annual customer-satisfaction surveys. Officials refuse to release the
