Performance - Gigabit LAN
Switching to a gigabit LAN connection removes a performance constraint, but only the Thecus appears to be able to really make the most of the higher-bandwidth LAN connection for writing. The rest of the pack stays clustered below the 100 Mbps LAN 12,500 Kbyte/sec line, with the NV+ once again besting the 1100.

Switching over to read spreads things out and speeds them up a bit. The NV+ and 1100 trade positions on file sizes up to 256 MB and then the NV+ comes out on top for 512 MB and 1 GB files. The Thecus N5200 once again displays the highest performance for smaller file sizes and drops off for larger. Like the Thecus, the Synology CS406 also shows decaying speed as file sizes increase, but consistently comes out last in this group for gigabit reads.

Enabling 4k jumbo frames provides a slight performance boost, but doesn't significantly change the rankings for gigabit writing. The NV+ seems to be helped the most for larger files.

Jumbo frames actually appears to lower performance for the NV+ and more so for the 1100. The original NV, however, gets a boost for smaller file sizes, as does the Synology, which again comes in lowest in ranking.
