fio features and specs

  • Highly Flexible
    Fio is highly configurable, allowing users to simulate various types of workloads with detailed parameters. This flexibility makes it suitable for a wide range of performance testing scenarios, including block devices, files, and networked filesystems.
  • Cross-Platform Compatibility
    Fio is designed to work on multiple operating systems, including Linux, Windows, and macOS. This cross-platform support enhances its usability in diverse environments and facilitates testing across different systems.
  • Rich Feature Set
    Fio supports a multitude of I/O engines, including sync, mmap, libaio, posixaio, and others. Additionally, it allows for dynamic generation of patterns, scripting via functions, and varied reporting formats, which are ideal for comprehensive performance analysis.
  • Active Development and Support
    Being an open-source tool with a large community, fio receives regular updates and improvements from contributors, ensuring that it remains robust and relevant for modern testing needs.
  • Detailed Reporting
    Fio provides detailed and customizable output formats, such as JSON and normal text, which help users analyze performance metrics in depth and facilitate easy integration into performance testing workflows.

Possible disadvantages of fio

  • Complexity for Beginners
    The extensive configuration options, while powerful, can be overwhelming for new users. It may take time and effort to learn how to effectively use fio and interpret its results without prior experience in performance testing.
  • Limited GUI Support
    Fio primarily operates from the command line, lacking a native graphical user interface (GUI). This can limit its accessibility for users who prefer visual tools and may require additional tooling or scripts for enhanced usability.
  • Resource-Intensive
    Running fio with complex workloads or on large-scale systems can be resource-intensive, potentially affecting other processes on the test system. Users need to ensure that appropriate resources are available to avoid skewed test results.
  • Steep Learning Curve for Advanced Features
    For users seeking to employ advanced features like custom scripting or network testing, understanding the full scope of fio's capabilities and configuration syntax can be challenging without comprehensive documentation or community support.

  • Dire SMB speed with on PC to NAS
    Assuming two systems use flash storage, network bandwidth is identical and it is configured the same way, there should be an issue within the PC, either system or storage drive. Check the system logs for errors and warning events related to data transfer from/to NAS. Try to benchmark the PCs' disks using fio to confirm they have similar performance. https://github.com/axboe/fio. Source: over 2 years ago
  • Ask HN: What are some good resources for learning about low level disk/file IO?
    Not specifically addressing your question, but when you get to the point of wanting to start doing some experiments you may find that 'fio' [1] is very handy. [1] https://github.com/axboe/fio. - Source: Hacker News / over 2 years ago
  • KVM virtual machines on ZFS benchmarks
    The dd is not a good benchmarking tool, you should use something like fio and probably tune it to use the ioengine most similar to your use case (eg. a database server will probably use some async IO interface). In your first example (with bs=1G) probably something (the guest OS, the qemu/kvm or the host OS) have split into smaller chunks anyway. Source: over 2 years ago
  • SSD Sequential Write Slowdowns
    All linux tests are run with fio 3.32 (github) with future commit 03900b0bf8af625bb43b10f0627b3c5947c3ff79 manually applied. Source: over 2 years ago
  • Just write the f*****g parser.
    Agree, I used flex/yacc to add an arithmetic expression evaluator to fio a few years back to allow simple math with some units in fio's job files, and for stuff like that, they're fine, but I wouldn't want to use them for a real language, the error handling is kind of a nightmare.

  • Why Is This Site Built with C
    Using a portable minimal markdown dependency (such as cmark [1]) I think markdown can be quite a low barrier here. I personally do similar to what you have described on my blog, with an additional cmark conversion and find it quite simple [2].

  • Ask HN: What's the simplest static website generator?
    I use GNU make. Write content in markdown, feed it to https://github.com/commonmark/cmark to create html. I intended to splice files together using xslt but echo and cat written in the makefile sufficed. I'm not totally sure I'd recommend that but I do like the markdown => html flow. - Source: Hacker News / over 1 year ago
  • Building a Personal Internet from Markdown Files
    I seem to be in the middle of trying to build something similar to this. I want it to run on an android phone but otherwise the same sort of idea, offline-first information I want access to. There's some weirdness around android browsers refusing to load html from the phone itself on security grounds. The OP uses a "progressive web app" which seems to be the proper way to do this at some point in the past, but... - Source: Hacker News / over 1 year ago
  • Using Rust with Elixir for code reuse and performance
    Yeah no doubt it, although in this case the C implementation has been a long running project that's under the official commonmark GitHub repo at https://github.com/commonmark/cmark. But I think the most important thing here is an Elixir NIF already exists to use it. The blog post as is leaves readers having to implement ~100 lines of Elixir code to use the Rust version because the authors of blog post didn't... - Source: Hacker News / about 4 years ago

    I'm confused about how to use a c library (specifically, cmark) from zig. Source: about 4 years ago
