I'm using a 400 MBps cable link here, directly connected, I can get 48 |
36 |
MBytes/s out of it (which should be very close if not even little above |
37 |
400 MBps), even when using the TP-Link as switch. If I use bridge mode |
38 |
and use TP-Link as router, it stop roughly around 300 MBps. My previous |
39 |
router even stopped at 30 MBps. It's a CPU issue. The internal CPU |
40 |
needs to do layer 3 routing. Layer 2 routing (switching) can be done by |
41 |
hardware. Login to your router and see how the CPU is loaded. Use top. |
42 |
If you still loaded it with its original hardware, you cannot do this, |
43 |
tho. Try OpenWRT (that is what I used). |
44 |
|
45 |
I think there's a database which contains throughput test results with |
46 |
different router hardware and different firmware. However, with a quick |
47 |
google search, I cannot find it. You may have more luck. |
