Folder Redirection, especially AppData, can still create nasty bottlenecks in the larger VDI / TS deployments. Microsoft just releases a tool that might be able to help out.
File server capacity planning and performance troubleshooting are critical aspects of high-level network administration. File server capacity planning tools can be valuable in choosing new hardware for purchase, identifying the capacity of existing hardware, locating existing bottlenecks, and planning for resource expansion in advance of resource exhaustion.
The throughput capacity of a file server can be expressed either as the maximum number of operations per second or a maximum number of users supported by the configuration. These values are influenced by several factors, some of which include processor speed, available memory, disk speed, network throughput and latency, and the speed with which SMB requests are processed.
This release is an updated release to v1.0. It includes support of File Server in the Windows Clustering configuration. Windows Clustering allows system to be built with redundancy, which provides high availability to tolerate hardware failures. With a two node clustering, you could setup more than one virtual file server instance, and have FSCT clients run load against all the instances. In this release, a new section “Running FSCT against a singleton Windows Cluster” will describe the setup and steps for running against a Windows Cluster.
