Heap and Allocation Profiling

Finding memory hotspots with heap profiles

Why heap profiling?

Excessive memory allocations slow Go programs through GC pressure. Heap profiling shows which code paths allocate the most memory so you can reduce allocations.

Capturing a heap profile

Via HTTP endpoint (requires net/http/pprof):

go tool pprof http://localhost:6060/debug/pprof/heap
