Function: benchmarkCompression()

function benchmarkCompression(
   data, 
   adapter, 
   iterations): object;

Defined in: persistence/src/compression.ts:346

Benchmarks a compression adapter's performance by running multiple iterations.

Performs a warm-up pass before measuring, then runs iterations rounds each of compress and decompress to compute average timings.

Parameters

Parameter	Type	Default value	Description
data	string	undefined	The input string to use for benchmarking.
adapter	CompressionAdapter	undefined	The compression adapter to benchmark.
iterations	number	100	Number of iterations for each operation. Higher values produce more stable results but take longer.

Returns

object

An object containing:

• ratio -- compressed size / original size (lower is better)
• compressTimeMs -- average compress time per iteration in milliseconds
• decompressTimeMs -- average decompress time per iteration in milliseconds
• originalSize -- length of the input string in characters
• compressedSize -- length of the compressed string in characters

compressedSize

compressedSize: number;

compressTimeMs

compressTimeMs: number;

decompressTimeMs

decompressTimeMs: number;

originalSize

originalSize: number;

ratio

ratio: number;

Example

const result = benchmarkCompression(largeJson, createLZCompressionAdapter(), 200);
console.log(`Ratio: ${result.ratio}, Compress: ${result.compressTimeMs}ms`);
