VisualVM features and specs

  • Comprehensive Monitoring
    VisualVM allows developers to monitor and troubleshoot Java applications through various data points like JVM-level statistics, thread monitoring, and memory inspection.
  • Integration with JDK
    As a part of the JDK, VisualVM is easy to access and use without the need for additional installations or configurations.
  • Lightweight
    Being lightweight, VisualVM does not add significant overhead to the system and can be used effectively in development without impacting performance.
  • User-friendly Interface
    VisualVM provides an intuitive and graphical interface that makes it easier for users to analyze the performance metrics and diagnose issues.
  • Plugin Support
    VisualVM supports plugins, allowing users to extend its functionalities according to specific requirements and use cases.
  • Cross-platform
    As a Java-based tool, VisualVM can be run on any platform that supports Java, making it highly versatile.

Possible disadvantages of VisualVM

  • Limited to Java Applications
    VisualVM can only be used with Java applications, which can be a limitation for mixed-environment monitoring needs.
  • Limited Features for Enterprise
    While excellent for basic monitoring, VisualVM might lack some features and scalability needed for large enterprise-grade monitoring and performance analysis.
  • Steep Learning Curve for Advanced Features
    Despite its user-friendly interface, some advanced features and customizations can be complex and may require a steep learning curve.
  • Infrequent Updates
    The update cycle for VisualVM can be slower compared to commercial alternatives, leading to potential lag in addressing bugs or adding new features.
  • Resource Usage
    Running VisualVM for in-depth analysis on the same machine as the application it monitors could potentially affect the application’s performance due to resource consumption.

Google Lighthouse features and specs

  • Comprehensive Audits
    Lighthouse performs a wide range of audits including performance, accessibility, SEO, and best practices, providing a holistic view of a website's overall health.
  • Open Source
    As an open-source tool, Google Lighthouse allows for transparency and flexibility, letting developers contribute to its improvement or customize it for their own use cases.
  • Automated
    Lighthouse can run automated audits on a site, saving time and effort compared to manual testing methods, and ensuring consistency in audit results.
  • Actionable Recommendations
    Lighthouse provides actionable recommendations and specific guidance on how to fix identified issues, helping developers and site owners make meaningful improvements.
  • Integration Friendly
    Lighthouse can be integrated into various development workflows and CI/CD processes through its CLI, Node module, or browser extension, enhancing its usability in diverse environments.

Possible disadvantages of Google Lighthouse

  • Performance Fluctuations
    Lighthouse performance scores can vary depending on different factors like network speed, hardware, and server response times, making it challenging to get consistent results.
  • Limited Context
    While Lighthouse provides specific issues, it may not fully account for the context of the website, potentially leading to recommendations that are not always the best fit for every scenario.
  • Not Real-User Data
    Lighthouse audits are based on synthetic testing, which might not always reflect real-user experiences accurately, limiting insights into how actual users interact with the site.
  • Learning Curve
    Less experienced developers may face a learning curve in understanding and implementing the recommendations provided by Lighthouse, particularly for more complex issues.
  • Dependency on Chrome
    As Lighthouse is built to work with Chrome, it may not fully capture site performance or issues when accessed through other browsers, potentially missing cross-browser compatibility problems.

  • Can java collection be fixed?
    If you're curious, attach VisualVM and watch the RAM usage graph. You'll notice that Java performs garbage collections long before reaching allocating the maximum amount of RAM allocated, and you can't even feel any performance issue in-game. Source: almost 2 years ago
  • Items won't drop when either mined or dropped from inventory and new chunks won't load.
    Hangs and deadlocks are significantly harder to debug. A first step is taking a thread dump so you can see what each thread in the JVM is currently trying to do. I like VisualVM for this, you can also use the command-line tools jps -l (to list all Java PIDs) and jstack for taking a thread dump. Source: almost 2 years ago
