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.
We have collected here some useful links to help you find out if fio is good.
Check the traffic stats of fio on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of fio on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of fio's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of fio on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.

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: about 3 years ago
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 / about 3 years ago
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 3 years ago
All linux tests are run with fio 3.32 (github) with future commit 03900b0bf8af625bb43b10f0627b3c5947c3ff79 manually applied. Source: over 3 years ago
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.

Luckily, newer Linux kernel versions support io_uring, a new asynchronous I/O interface. But would it help in our case? Learning the answer is simple and, in fact, doesn't even require a single line of code, thanks to fio, a very flexible I/O tester utility. - Source: dev.to / almost 4 years ago

Basically io_uring grew a lot, the latest API offers incredible tools but there are very few examples in any language (xnvme and fio), and in particular I'm struggling to understand how to do it in Rust: where should unsafe code stop? Should I simply expose the io_uring api as unsafe, or should I do more work in C and present the ring when ready to rust? Source: almost 4 years ago
Hdparm is an "okay" tool for a quick read speed benchmark, but if you really want to benchmark Linux storage, its hard to beat fio[0] [0] https://github.com/axboe/fio. - Source: Hacker News / about 4 years ago
I would try to avoid reading from the same drive what I am actually test, too. You can try the fio tool. Source: about 4 years ago
This use of dt, etc, is pretty cool, and I understand the point of this this blog entry was an exploration of those tool. But in the wider world of SSD performance, you're going to want more. fio (written by Jens Axboe, who's responsible for a lot of the I/O subsystem in Linux) is the standard tool used to do benchmarking, has tons of options to control I/O mix and parallelism, captures both thruput and latency... - Source: Hacker News / about 4 years ago
When it comes to generating artificial storage workloads, the right answer is almost always to just use fio: https://github.com/axboe/fio and specifically https://fio.readthedocs.io/en/latest/fio_doc.html#i-o-rate. Source: over 4 years ago
