Instruments are a key component of CodSpeed. They are used to measure the performance of your code using different techniques.

​
Executor Instruments

CPU Simulation

Measure performance by simulating the CPU behavior

Memory

Track memory usage, allocations, and leaks in your benchmarks

Walltime

Measure performance by measuring the real time taken

​
Ad Hoc Instruments

Those ad hoc instruments can be used on top of an executor instrument to measure specific performance metrics.

Database Instrument

Measure the performance of database queries
