Why Software Keeps Getting Slower on Faster Hardware

Processors, memory and storage have improved by extraordinary margins over two decades. The experience of using everyday software has not improved proportionately, and in several respects has regressed. The reasons are structural rather than technical incompetence.

Available capacity gets consumed

Performance headroom is treated as a resource to spend. Faster hardware permits more abstraction layers, larger frameworks and less optimisation — each individually reasonable, collectively absorbing the gains. This is well understood in the industry and consistently repeated, because the alternative costs development time.

Cross-platform frameworks trade efficiency for reach

Building one application that runs everywhere is enormously valuable commercially. It also means shipping an entire browser engine with a text editor, and accepting startup times and memory usage far above what a native application would require. The trade is deliberate, and the cost lands on the user rather than the developer.

Network dependency replaced local capability

Software that once operated locally now waits on servers for operations that could be performed on the device. Every such call adds latency that no local hardware improvement can reduce. Applications increasingly feel slow because they are waiting rather than computing.

Development environments hide the problem

Software is built on high-specification machines with fast, reliable connections, and tested in the same conditions. Performance problems that are severe on an older device or a poor connection are invisible to the people building it — which is why applications frequently feel dramatically worse outside the developer’s environment.

Nothing measures this

Feature delivery is tracked and rewarded. Startup time, memory footprint and responsiveness usually are not, so they drift. Teams that treat performance as a tracked metric with a budget maintain it; those that do not lose it gradually and without anyone deciding to.

The hardware kept its side of the bargain. What was gained has largely been spent on developer convenience, which is a defensible choice that users were never consulted about.
