Some VMware users looking to run more virtual machines per host have found that InovaWave's DXtreme performance optimization software can get them up to two times as many virtual machines (VM) per host without increasing hardware resources like RAM.

Sound too good to be true? That's what Rob Hirschfeld thought when former co-worker and InovaWave CTO Dave McCrory told him that DXtreme could make his VMs run faster than if they were on physical hardware. "I told him he was full of it," Hirschfeld recalls.

But as chief architect overseeing a team of engineers at NovusEdge, an asset management software developer in Austin, Texas, Hirschfeld knew that getting better performance out of VMware Workstation was important to his team. As it stood, developers found that they could either run Eclipse, their integrated development environment (IDE), or test VMs with VMware Workstation – but not both. "Developers' time is at a premium," he said.

When he tested DXtreme, Hirschfeld found that he could in fact run about two times as many VMs with his given hardware, or he could run the same number of VMs and also run his IDE. At the same time, Hirschfeld witnessed first-hand an oddity of DXtreme: that VMs will run faster if you give them less RAM.

"It's a paradox," Hirshfeld said. "They tell you to reduce the RAM, and you think, 'That's not going to make you go faster.' Then you do it, and it does."
