Several big files move more quickly from my LAN file server compared to smaller ones.
Several big files move more quickly from my LAN file server compared to smaller ones.
Hey everyone! I've got several Linux ISOs set up on my file server. After switching to Gigabit networking with my routers and cables, I started testing speeds. Some files moved smoothly from the HDD on my server to the SSD on my PC at full Gigabit, but another file would jump to Gigabit initially then slow down to around 250Mbps afterward. When I copied the same file back from my PC to the server's HDD, it worked perfectly at Gigabit. I'm using Linux Mint 20.3 on the server with a dedicated HDD and a Windows 11 PC. I'm just copying files via File Explorer between network and local drives. Any thoughts on what's happening? Also, a bit of extra info – I'm on its own dedicated HDD for the shared folder, and my computer is running Windows 11. Thanks!
It might be due to fragmentation or even bad sectors on the HDD. Excessive movement of the head during copying can significantly reduce performance. If error correction is heavily used, this could also impact speed. After saving the file, does the process repeat from the new position and become slower again?
