// CONCLUSION: The overhead for the map is negligible. Text format needs ~5x more allocations.
// Without compression, it needs ~7x longer, but with compression (the more relevant scenario),
// the difference becomes less relevant, only ~4x.

// The test data contains 248 samples.

// BenchmarkProcessor002ParseOnly in the extraction package is not quite
// comparable to the benchmarks here, but it gives an idea: JSON parsing is even
// slower than text parsing and needs a comparable amount of allocs.
