Top 23 Java Performance Projects
-
-
Pinpoint is a performance monitoring tool for Python, Java, and PHP applications. It can monitor CPU, memory, and storage utilization. You can integrate it into your project without changing a single line of code.
-
SonarQube
Static code analysis for 29 languages.. Your projects are multi-language. So is SonarQube analysis. Find Bugs, Vulnerabilities, Security Hotspots, and Code Smells so you can release quality code every time. Get started analyzing your projects today for free.

Choosing a language is a significant factor towards the performance of your services.
A service built in go can req/resp up to 30x faster than one built in python.

I know benchmarking isn't always the greatest, especially when the previous maintainer of Actix-Web (Rust) kind of cheated to get to the top of the leaderboard, but it still provides a decent general overview of how many responses/s a service can handle when using the same box.

OrientDB
OrientDB is the most versatile DBMS supporting Graph, Document, Reactive, Full-Text and Geospatial models in one Multi-Model product. OrientDB can run distributed (Multi-Master), supports SQL, ACID Transactions, Full-Text indexing and Reactive Queries.
I think the best multi-modal with a high focus on their graph-side outside of Neo4j for the last few years has been OrientDB.

Project mention: Best way to store nosql data locally on Android device? | reddit.com/r/androiddev | 2021-12-15
Maybe this? I've been looking at it recently.

-
Scout APM
Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.

💻 GitHub
-
AndroidGodEye
An app performance monitor(APM) , like "Android Studio profiler", you can easily monitor the performance of your app real time in browser
-
ANR-WatchDog
A simple watchdog that detects Android ANR (Application Not Responding) error and throws a meaningful exception
-
Project mention: Are you interested in learning about low latency zero allocation programming? | reddit.com/r/java | 2021-02-06
-
Scouter is a powerful tool that can monitor Redis, Nginx, Kafka, MongoDB, Kubernetes, and other sources. It can monitor CPU, memory network and heap utilization, active users, active services, and more.
-
Stagemonitor
an open source solution to application performance monitoring for java server applications
🌐 Website 💻 GitHub
-
Automon
Automon combines the power of AOP (AspectJ) with monitoring or logging tools you already use to declaratively monitor your Java code, the JDK, and 3rd party libraries.

Project mention: how to create an excel file from a form in an android app | reddit.com/r/androiddev | 2021-12-14
I would use some library like for example this one. So you collect all the data you want to store in a list or map, and iterate over it, then add them to the excel like shown in the documentation of the library (should always be the same way more or less for any library)
-
quickperf
QuickPerf is a testing library for Java to quickly evaluate and improve some performance-related properties
-
Project mention: OptiFine alternatives? More specifically looking for mods that allow for OptiFine textures. | reddit.com/r/fabricmc | 2022-01-23
I like custom textures but so many of them require OptiFine. I already have a bunch of OptiFine alternatives. I have Sodium, FerriteCore, C2ME, LambDynamicLights, Starlight, and Sodium Extra. I have looked at Animatica but that only allowed for animated textures. Do you guys know of any mods that allow for OptiFine textures but work with my performance mods?
-
parallel-consumer
Parallel Apache Kafka client wrapper with client side queueing, a simpler consumer/producer API with key concurrency and extendable non-blocking IO processing.
Project mention: How many different groups/consumers for X topics? | reddit.com/r/apachekafka | 2021-12-12Interesting. I think your use case might be well suited for the parallel consumer — https://github.com/confluentinc/parallel-consumer
-
even according to XSeries it should be that...

are-we-fast-yet
Are We Fast Yet? Comparing Language Implementations with Objects, Closures, and Arrays
> Software benchmarks are super subjective.
No, they are not, but they are just a measurement tool, not a source of absolute thruth. When I studied engineering at ETH we learned "Who measures measures rubbish!" ("Wer misst misst Mist!" in German). Every measurement has errors and being aware of these errors and coping with it is part of the engineering profession. The problem with programming language benchmarks is often that the goal is to win by all means; to compare as fairly and objectively as possible instead, there must be a set of suitable rules adhered to by all benchmark implementations. Such a set of rules is e.g. given for the Are-we-fast-yet suite (https://github.com/smarr/are-we-fast-yet).
