MultiPing will generate a html based report to help troubleshoot network problems.

PowerShell module to determine the network latency between two Azure regions.

Universal latency diagnostics: Internet/WAN, DNS, SMB/File shares (NetApp), reporting. Safe-by-default + explain mode + real transfer tests (HTTP download + SMB copy) with overwrite + file size options.

Windows network diagnostics toolkit — connectivity testing, DNS analysis, port scanning, latency measurement, and network adapter monitoring

PS-PING is a real-time ping/latency monitor for Windows. It graphs round-trip time, timeouts and packet loss per target in an interactive, 100% offline HTML dashboard (Chart.js). Single self-contained PowerShell script, no external dependency, runs on Windows PowerShell 5.1 and PowerShell 7+ (strict ConstrainedLanguage compatible).

This script disables CPU core parking (CPMINCORES/CPMINCORES1 = 100%) and sets Energy Performance Preference (PERFEPP/PERFEPP1 = 0) on the current power scheme. Supports Intel 12th gen+ hybrid CPUs (separate P-core/E-core settings) and traditional non-hybrid CPUs (AMD Ryzen, older Intel). Class 1 (P-core) settings that don't exist on non-hybrid CP...

Lists PCI devices, shows their MSI status in Out-GridView, and enables MSI for the devices you select. Zero external dependencies. Windows PowerShell 5.1+.

Shows the current state of the Windows timer stack (timer resolution, bcdedit timer tweaks, HPET, Windows 11 global resolution requests), measures real Sleep(1) precision, and applies the tweaks you select in a grid - each one opt-in, with a JSON undo file and a full BCD backup written before any change. Zero external dependencies.

Lists PCI devices with their current interrupt affinity policy in Out-GridView, then pins the interrupts of the devices you select to the CPU cores you pick in a second grid (P/E-cores labeled on hybrid CPUs). Writes the documented DevicePolicy / AssignmentSetOverride registry values. Zero external dependencies. Windows PowerShell 5.1+.
