Server benchmark and burn in software.
Server Benchmark [s.b] allows server engineers and administrators to quickly complete the "burn in" phase of your server and VDI provisioning process. The software also allows users to benchmark processing and memory utilization by dynamically adding threads and building arrays to test memory capacity. Server Benchmark is also a great way to maximize capacity and test response from within your existing Citrix XenApp farm, and VDI infrastructure. Source code is attached to the "Source" folder.
