Hardware Stress API for .NET

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.

📝 Requirements

Visual Studio.

Usage

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.

CPU Stress

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

Memory Stress

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

Disk Stress

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))
End Using
