• 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: 11 months 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 / about 1 year 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: about 1 year ago

• SSD Sequential Write Slowdowns

  All linux tests are run with fio 3.32 (github) with future commit 03900b0bf8af625bb43b10f0627b3c5947c3ff79 manually applied. Source: over 1 year 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.

• How to Setup a Project That Can Host Up to 1000 Users for Free

  Logging is useful to explain the non-exceptional behavior of the application. It provides an audit trail, that can be used to understand the activities of complex systems, to diagnose problems, and to gather performance-relevant data. Logentries is a powerful log management tool. It offers a nice graphic representation of log data through web UI. It integrates with New Relic, providing combined search across both... - Source: dev.to / 6 days ago

• How to improve page load speed and response times: A comprehensive guide

  These tools track server and underlying infrastructure and backend performance. They monitor several metrics, like disk I/O, CPU and memory usage, network traffic, and more. Some examples of these tools include New Relic, Datadog, and AppDynamics. Web administrators can use them to see what's causing slow SRT, like high CPU usage or network traffic. Server-side monitoring tools also provide real-time alerts to... - Source: dev.to / 4 months ago
