Windows filecopy tests were run using the standard NAS testbed connected to a router Gigabit LAN port and our standard USB 3.0 drive formatted in FAT32 and NTFS connected via the USB 2.0 port.
I created this table to compare the ESR1750 file copy performance with other AC1750 class routers. I also included the EnGenius ESR1200. Both EnGenius routers turned in very similar results with relatively poor NTFS Write performance. However, both outperformed the two BCM4706-based routers (NETGEAR and ASUS) on all tests except for NTFS Write.

Routing performance for the ESR1750 loaded with 1.1.0 firmware (upgraded from 1.0.1) and using our standard test method is summarized in the table below. I also included the results for the ESR1200 for comparison.
Since both routers have the same processor, I had expected the routing performance to be almost identical. Indeed, the WAN to LAN and LAN to WAN results were virtually the same. Surprisingly, however, for the simultaneous throughput test, the ESR1750 significantly outperformed the ESR1200.
|Test Description||EnGenius ESR1750||EnGenius ESR1200|
|WAN - LAN||335.3||333.6|
|LAN - WAN||322.3||320.3|
|Maximum Simultaneous Connections||30,126||30,437|
Table 4: Routing throughput
The results for both the WAN to LAN and LAN to WAN tests were significantly lower than those of competing AC1750 class routers. The ESR1750 ranked 10/11 for WAN to LAN performance and 11/11 (last place) for LAN to WAN. The performance leader for WAN to LAN was the D-Link DIR-868L at 942 Mbps; for LAN to WAN, the leader was the TP-LINK Archer C7 at 942.9 Mbps. Both were running virtually at Gigabit wire speed. Still, with most consumer broadband connections running at less than 50 Mbps, the relatively low performance won’t have any noticeable impact.
For the unidirectional tests, the IxChariot chart below shows steady throughput at almost the same level. This chart is almost identical to the unidirectional chart for the ESR1200.

The story for the simultaneous up/downlink tests was quite different as compared to the ESR1200. The ESR1200 heavily favored uplink (Avg 240 Mbps) as compared to downlink (Avg 67.4 Mbps). The ESR1750 heavily favored downlink (Avg 333.3 Mbps) as compared to uplink (Avg 261.6 Mbps). Tests for both uplink and downlink showed more consistent performance with less variation.

Part of the reason for the relatively poor routing performance is because the ESR1750 defaults the "Network Turbine" setting to off. This is the "Fast NAT" option that many current-generation routers now enable by default. Since enabling the feature on the EnGenius requires turning DLNA off and displays the ominous message below, tests weren't run with Network Turbine enabled.
