A .NET class library written in VB.NET, that provides a mechanism for exerting pressure on hardware resources, such as CPU, RAM, or disk drives.
- Visual Studio.

Usage is very simple, there are 3 classes: CpuStress, DiskStress and MemoryStress, which provides an Allocate() method to start stressing resources, and a Deallocate() method to stop it.
Using cpuStress As New CpuStress()
Dim percentage As Single = 20.5F 20.50%
Console.WriteLine("Allocating CPU usage percentage...")
cpuStress.Allocate(percentage)
Thread.Sleep(TimeSpan.FromSeconds(5))
Console.WriteLine("Instance CPU average usage percentage: {0:F2}%", cpuStress.InstanceCpuPercentage)
Console.WriteLine("Process CPU average usage percentage: {0:F2}%", cpuStress.ProcessCpuPercentage)
Console.WriteLine()
Console.WriteLine("Deallocating CPU usage percentage...")
cpuStress.Deallocate()
Thread.Sleep(TimeSpan.FromSeconds(5))
Console.WriteLine("Instance CPU average usage percentage: {0:F2}%", cpuStress.InstanceCpuPercentage)
Console.WriteLine("Process CPU average usage percentage: {0:F2}%", cpuStress.ProcessCpuPercentage)
End Using
Using memStress As New MemoryStress()
Dim memorySize As Long = 1073741824 1 GB
Console.WriteLine("Allocating physical memory size...")
memStress.Allocate(memorySize)
Console.WriteLine("Instance Physical Memory Size (in bytes): {0} ({1:F2} GB)", memStress.InstancePhysicalMemorySize, (memStress.InstancePhysicalMemorySize / 1024.0F ^ 3))
Console.WriteLine("Process Physical Memory Size (in bytes): {0} ({1:F2} GB)", memStress.ProcessPhysicalMemorySize, (memStress.ProcessPhysicalMemorySize / 1024.0F ^ 3))
Console.WriteLine()
Console.WriteLine("Deallocating physical memory size...")
memStress.Deallocate()
Console.WriteLine("Instance Physical Memory Size (in bytes): {0}", memStress.InstancePhysicalMemorySize)
Console.WriteLine("Process Physical Memory Size (in bytes): {0} ({1:F2} MB)", memStress.ProcessPhysicalMemorySize, (memStress.ProcessPhysicalMemorySize / 1024.0F ^ 2))
End Using
Using diskStress As New DiskStress()
Console.WriteLine("Allocating disk I/O read and write operations...")
diskStress.Allocate(fileSize:=1048576) 1 MB
Thread.Sleep(TimeSpan.FromSeconds(10))
Console.WriteLine("Stopping disk I/O read and write operations...")
diskStress.Deallocate()
Console.WriteLine()
Console.WriteLine("Instance disk I/O read operations count: {0} (total of files read)", diskStress.InstanceReadCount)
Console.WriteLine("Process disk I/O read operations count: {0}", diskStress.ProcessReadCount)
Console.WriteLine()
Console.WriteLine("Instance disk I/O read data (in bytes): {0} ({1:F2} GB)", diskStress.InstanceReadBytes, (diskStress.InstanceReadBytes / 1024.0F ^ 3))
Console.WriteLine("Process disk I/O read data (in bytes): {0} ({1:F2} GB)", diskStress.ProcessReadBytes, (diskStress.ProcessReadBytes / 1024.0F ^ 3))
Console.WriteLine()
Console.WriteLine("Instance disk I/O write operations count: {0} (total of files written)", diskStress.InstanceWriteCount)
Console.WriteLine("Process disk I/O write operations count: {0}", diskStress.ProcessWriteCount)
Console.WriteLine()
Console.WriteLine("Instance disk I/O written data (in bytes): {0} ({1:F2} GB)", diskStress.InstanceWriteBytes, (diskStress.InstanceWriteBytes / 1024.0F ^ 3))
Console.WriteLine("Process disk I/O written data (in bytes): {0} ({1:F2} GB)", diskStress.ProcessWriteBytes, (diskStress.ProcessWriteBytes / 1024.0F ^ 3))
