Why you should use NFSv4 over NFSv3 in your Proxmox cluster - the difference is huge!

And if NFS has still too high latencies for you, my upcoming post of NVMe-oF (TCP) with SPDK will solve your issues.

Link: https://gyptazy.com/nfsv3-vs-nfsv4-storage-on-proxmox-the-latency-clash-that-reveals-more-than-you-think/

Not even bad the latency (this is just about latency, not overall bandwidth which reaches the full 4.9Gbit via 2x 2.5Gbit links).

Taken inside a Debian VM running on a Proxmox node connected to the storage:

GMKTec G9 NAS
2x 2.5Gbit
NFS 4.2 (with pNFS)
2x WD Back SN7100 NVMe
Mirror mode ZFS

While this are already pretty awesome latencies, let's see how it performs with SPDK and NVMe-oF (TCP).

#LibreQoS Launches #Bufferbloat Testing Platform:

https://libreqos.io/2025/06/13/bloat-test/

Traditional speed tests only tell part of the story. We tried to address @mtaht's points from “What’s Wrong with Speed Tests” article to make a better #speedtest that measures #WorkingLatency, #LatencyUnderLoad, and #jitter.

We will be at the booth no. 630, see you there!

I built a latency meter with an Arduino and a photo transistor to answer one question: Is click-to-photon latency higher on Wayland than on X11?

And the answer is: Yes, actually.

42 ms on X11, compositing off
56 ms on X11, compositing on
64 ms on Wayland
71 ms on Windows 10

Tested with Plasma 6.3.4 and Firefox 137. I will improve my methods and confirm these numbers. See replies for details.

→ Nigerians are building affordable alternatives to AWS and #Google Cloud
https://restofworld.org/2025/aws-google-cloud-nigeria-alternatives/

“The payments to #AWS gradually skyrocketed as the naira depreciated around 70% against the #dollar between 2020 and 2024”

“Besides the option to pay in #naira, these companies allow #Nigerians to store their #data within the #country — an advantage most of their Western rivals lack. #Local servers give businesses the benefits of low #latency and data #localization […].”

So I got the Anker K20I earbuds. They sound okay, but the latency is almost too much to deal with on Android. And of course, the only codecs they have for HD audio are SBC and AAC, cause Apple, gotta have that AAC. Game mode does nothing that I can tell. But they would be good earbuds for walking around listening to a book.
