maximising network file transfer speed

on a 1Gbps LAN, the theoretical transfer speed is 1024/8=128MB/s. but my experience of copying files between PCs and/or NAS through LAN is in the range of Kb/s or a few MB/s, an extremely far cry from the theoretical speed. my guess is that the limitation is in the software or OS. did a quick search on how to improve network transfer speed, many “solutions” out there, but the tip from howtosolutions.net appears to effect some improvement in speed:

1. Disable LSO (Large Send Offload) found in Advanced settings of network card in Windows Device Manager.

2. Enable and maximise the value of “Jumbo Packet” in Advanced settings (this is found in the comments within the above post)

works on physical LAN. not sure if it works for WiFi connections though.
