🐕 qq-benchmark

qq-benchmark is a Kotlin library that can benchmark your code snippets with beautiful console output.

How to use

• Just copy and paste Single-File version QBenchmark.kt into your project.
• Or you can use Jar version. See Maven Dependency Section.
• Feel free to fork or copy to your own codebase 😍

code example

Full Source : QBenchmarkExample.kt

qBenchmark {
    // Number of trials
    nTry = 500

    // If this instance has several [block]s, it will shuffle them in randomized order and measure the time.
    // [nSingleMeasureLoop] represents how many times a block is executed in one measurement.
    // Eventually, the code snippet in the [block] will be executed [nSingleMeasureLoop] * [nTry] times.
    nSingleMeasureLoop = 5

    // In the early executions, the execution of the [block] takes more time,
    // so we first perform some executions which are not counted in the measurements.
    nWarmUpTry = 50

    block("Raw String Concat") {
        var str = ""
        for (i in 1..3000) {
            str += i.toString()
        }
        str
    }

    block("StringBuilder") {
        val sb = StringBuilder()
        for (i in 1..3000) {
            sb.append(i.toString())
        }
        sb.toString()
    }

    block("StringBuffer") {
        val sb = StringBuffer()
        for (i in 1..3000) {
            sb.append(i.toString())
        }
        sb.toString()
    }
}

Please see QBenchmarkTest.kt for more code examples. Single-File version src-test-single/QBenchmarkTest.kt is a self-contained source code that includes a runnable main function. You can easily copy and paste it into your codebase.

Public API

• qBenchmark() function
• QBenchmark class

Single-File version Dependency

If you copy & paste QBenchmark.kt, fefer to build.gradle.kts to directly check project settings.

dependencies {
    implementation("org.jetbrains.kotlin:kotlin-reflect:1.8.20")
    implementation("org.jetbrains.kotlin:kotlin-stdlib:1.8.20")
}

Jar version Maven Dependency

If you prefer a jar library, you can use jitpack.io repository.

build.gradle ( Groovy )

repositories {
    ...
    maven { url 'https://jitpack.io' }
}

dependencies {
    implementation 'com.github.nyabkun:qq-benchmark:v2023-05-28'
}

build.gradle.kts ( Kotlin )

repositories {
    ...
    maven("https://jitpack.io")
}

dependencies {
    implementation("com.github.nyabkun:qq-benchmark:v2023-05-28")
}

pom.xml

        <id>jitpack.io</id>
        <url>https://jitpack.io</url>

How did I create this library

• This library was created using qq-compact-lib to generates a compact, self-contained library.
• qq-compact-lib is a Kotlin library that can extract code elements from your codebase and make a compact library.
• It utilizes PSI to resolve function calls and class references.
• The original repository is currently being organized, and I'm gradually extracting and publishing smaller libraries.
