Attempting to achieve 2GB/s from two 10GbE connections on a single PC
Attempting to achieve 2GB/s from two 10GbE connections on a single PC
Hey team! I'm working with two Windows 10 systems, each equipped with a dual 10GbE port using an Intel X550 adapter. All four ports connect to a single 10GbE switch. I spent a lot of time exploring different setups before realizing the SMB multichannel mode works surprisingly well. (Seriously, don't use link aggregation if you're after maximum speed!) Right now I'm achieving around 1.3GB/s, but my goal is to hit close to the full 20Gbit theoretical limit. I've verified that during file transfers both ports are active and sending data evenly. The crystal disk mark confirms that one machine has an M.2 drive while the other holds five 1TB SSDs in a compact storage layout with five columns—both capable of over 2GB/s read/write speeds. So what's still missing to push performance further? Here are some images that might help clarify your questions...

A solid inquiry, though both devices seem to be accessing the PCIe 3.0 provision through the CPU instead of the chipset, meaning they’re both operating in PCIe 3.0 4x (3.8GB/s). The NAS lacks a dedicated video card and relies entirely on the CPU for processing. PC NAS
You're asking about the NAS's storage setup. It's using a specific filesystem, likely one of the standard options like NTFS or FAT32. The drives are probably arranged in a RAID configuration for redundancy and performance. Regarding your transfer, it seems you're moving a game folder or possibly a compressed archive (.zip), not just a single file.
NTFS and... Observe that the area in discussion is known as "Fast space." Five columns indicate data is spread across all five drives, making it function like RAID 0, which accounts for the high speeds listed. The interface displays (remember GUI can't adjust columns, so issues might stem from that) a single large MKV file being moved. Running several files simultaneously doesn’t slow things down, but it adds more disk workload, yet the task manager reports no maximum usage, suggesting we’re not hitting storage limits.
Just to verify the speeds, I removed one cable from each connection during transfer. It continued transferring without stopping, though it became stuck when both were present. It took a few minutes to resume using both ports after replugging everything back in. I noted the maximum speed with one cable per port is 1.08GB/s, and with two cables it reached 1.47GB/s. I’m generally satisfied, but feel free to point out any improvements you discover in the future!
