Latency (Ping):

For gaming, the driver performs adequately. The conversion from USB to Ethernet adds a negligible amount of latency (approx. 1–2ms). However, because it relies on the CPU to manage the USB data transfer (unlike a dedicated PCIe card), CPU usage can spike slightly during heavy downloads, which might cause micro-stutters on very old computers. jp1081b usb lan driver 21

Unlike its more expensive cousins (like the AX88179 or RTL8153), the JP1081B focuses on providing basic, stable 100Mbps connectivity. It is ideal for: Comprehensive Guide to the JP1081B USB LAN Driver

• Max throughput: ~880–940 Mbps (real-world, close to Gigabit)
• CPU usage: Low to moderate (5–15% on a modern CPU)
• Latency: Adds 0.2–0.5 ms compared to onboard NIC
• Stability: Generally good with v21; older versions (v15–v18) reportedly had random disconnects.
