Ktor Benchmarks

This repository contains benchmark tests for various performance metrics.

Allocation Benchmark (/allocation-benchmark)

Tests how much memory is allocated on a given request. This is done before every merge to ensure that the ktor server maintains a low memory profile by avoiding erroneous allocations.

Testing: ServerCallAllocationTest runs through the supported engines and calculates the memory allocated per request. When a new baseline is required, you may run the dumpAllocations gradle target.

Inspection: the allocation baseline dump is a series of JSON files. For easy reading of the values exported here, use the reportServer gradle target which has two pages for inspecting where memory is being allocated. previewClasses.html shows the largest memory consumers for types allocated, and previewSites.html shows the code sites that allocate the most memory.
