Although I don't know the answer, I wanted to suggest using Amazon EC2 as a way you could determine this for your specific application.
You could provision two instances, use them for a few hours, then suspend or delete them. Even with the largest instance types it would probably cost ~$15 for say 8 hours. Going forward you could purchase similar hardware, or rent from Amazon on one of several commitment levels. Maybe you'd want a Linux and Windows flavor each of this instance type: >> High-CPU Extra Large Instance 7 GiB of memory 20 EC2 Compute Units (8 virtual cores with 2.5 EC2 Compute Units each) 1690 GB of instance storage 64-bit platform I/O Performance: High EBS-Optimized Available: No API name: c1.xlarge << Source: http://aws.amazon.com/ec2/instance-types/ That looks like US$0.66 per hour for Linux, $1.14 for Windows. (You're paying the Windows license fee as part of the latter.) Source: http://aws.amazon.com/ec2/pricing/ My guess is the Linux box will perform slightly better; also more cost-effective. But you could see for yourself.
