+    ],
+    dependencies: [
+        .package(path: "../"),
+        .package(url: "https://github.com/ordo-one/package-benchmark.git", exact: "1.11.1"),


I'd suggest to use from:, or at least bump to a recent version (.e.g, 1.18.0) - 1.11.1 is quite old by now and NIO has from rather than exact.

I realised this too, but had an issue with the latest build. I don't remember what it was, I believe my SPM caches were broken

Ok, @Joannis let me know if you have any issues with the package itself, 1.20 just released with quite a few fixes visavi 1.11.

+    let resp3ArrayValueBuffer = ByteBuffer(string: "*2\r\n$3\r\nGET\r\n$7\r\nwelcome\r\n")
+    let resp3ArrayCount = 2
+
+    Benchmark("RESP3 Array Parsing") { benchmark in


Suggested change

Benchmark("RESP3 Array Parsing") { benchmark in

Benchmark("RESP3 Array Parsing", configuration: .init(scalingFactor: .kilo)) { benchmark in

for _ in benchmark.scaledIterations {

try runRESP3ArrayParsing(

valueBuffer: resp3ArrayValueBuffer,

valueCount: resp3ArrayCount

)

}

Would suggest using such scaling factor (.kilo) for the RESP Array Parsing and RESP3 Array Parsing benchmarks, as they have very short runtimes. The scaling factor is used as an inner loop and the results will be scaled up accordingly for throughput if you update to a recent benchmark version.
