Bottleneck finds what is actually slowing your Windows PC

Field notes

Bottleneck runs short CPU, memory, disk, and graphics benchmarks, then compares the results with a reference dataset before ranking likely sources of lost performance. Findings include explanations, settings changes, and hardware recommendations rather than scores alone; scans can also be retained for trend tracking and exported as printable HTML reports. The homepage says the application can run from a USB stick, checks licence keys offline, and adds fleet comparison to Technician and higher licences.
