10 Gigabit
10 Gigabit
Hello, I'm checking if I should use a switch to link my desktop with my NAS via SFTP+. I've had mixed results—sometimes it runs at 10 gigabit, other times not. I'm unsure if a switch is necessary or if another issue exists. The setup uses an SFTP+ cable and the same network card on both devices.
Thanks for the details. It feels odd that sometimes large files move quickly while others take ages, even on your 2800x screen with an SSD. You mentioned using a Pentimento CPU and a Samsung M.2 cache, which helps. Maybe it’s related to how your system handles naps or background processes?
10 Gig offers exceptional speed! Various factors affecting your system or NAS might prevent you from achieving those speeds. If your NAS uses mechanical drives, they won’t perform as well, unless you’re transferring data that’s already stored. Be aware that contemporary SSDs use multi-layered NAND technology, which boosts storage density but can reduce speed. Every SSD includes a single-layer area for rapid writing, later transitioned to multi-layer storage. Utilizing all of this capacity will noticeably lower performance. Samsung Pro SSDs provide more single-layer space, while standard EVO models offer limited storage. Once the single-layer portion is exhausted, speeds drop significantly until the drive can reorganize data. It functions adequately for everyday tasks but may cause slowdowns during large file transfers. For testing network connections, tools like iperf are recommended if your NAS supports them. File copying often involves many variables, making it unlikely to hit the 10 Gig limit with current consumer hardware. This doesn’t mean 10 Gig is useless—you’re likely surpassing 1 Gig, though not necessarily reaching the full potential.
I don't share your view on this. The network stacks weren't built with 10G in mind; they were crafted for smooth performance with minimal overhead and can handle both bit/sec and pps effectively. While it's true Windows can generate a lot of broadcast traffic, that doesn't mean its networking is flawed—its stack performs adequately.
Sorry you don't see eye to eye, but my tests confirm otherwise. No problems with reaching 10G bandwidth through a single TCP stream using iperf on Linux. It's straightforward and stable—no hiccups. Give it a try with a single TCP connection in Windows 10, even if you're offline. This is purely memory-to-memory, with no extra delays. Make sure to read the white paper carefully to understand what I'm saying.
