A gigabit switch paired with a 100mbit router
Hi! You're dealing with a setup where high-speed devices are connected through a gigabit switch, but you're experiencing performance issues when transferring large amounts of data. It sounds like the bottleneck comes from flash speed limitations on one device, which caps the maximum throughput. When you send a 200Mbps file from your PC to device001, it's being slowed down by that flash speed. At the same time, a download from an external server is also happening, and the interference is reducing the download speed significantly. This shouldn't happen if the switch isn't near its limit, so the issue likely lies with the PC's network card (Realtek 8111GR) and how it negotiates links. Upgrading to newer drives or ensuring proper link settings might help.
It might be due to reaching the CPU's capacity because it's taking a long time to wait for a reply from the 200Mbit device. This can slow down your entire PC even though you think otherwise. The connection speed won't exceed 10/100/1000 Mbps, but the issue could stem from the Realtek Ethernet card. It's usually better to use Intel network cards for the best results.
