Delicious Timer is a fast, lightweight profiler oriented towards execution speed.

It makes it easy to visualise what happens in your program and lets you quickly spot opportunities for speed-ups.

Some key points:

  • Delicious Timer is fast: it can record up to millions of time lapses per second.

  • It is easy to navigate: it feels snappy and responsive, even when there is tons of data to display.

  • You can get the statistics you care about: the visualiser lets you instantly combine threads, compute local statistics, sort results and search through them. You can also highlight locks and memory allocations throughout your program.

  • Get it up and running within minutes: the Delicious Timer API is simple and straightforward. You can disable it at any time with one line of code.

  • Easily record time lapses, context switches, thread locks and memory allocations.

  • Bloat-free: Delicious Timer is fully portable and weighs less than a megabyte.


For now only Windows is supported, there are plans for a Linux version.

  • Windows 10, 11 (other versions remain untested)
  • A modern AMD64 (x64) CPU (anything from the last 10 years should do)
  • Lots of RAM if you plan to record tons of timelapses (memory usage is proportional to the number of time lapses recorded)
