Ubiquiti EdgeRouter X, Loading OpenWrt and performance numbers

Hardware Questions and Recommendations
27

Sorry that it took me a while to figure out how to setup sqm.

TLDR:
At 16 threads, SQM seem to max out around 200Mbps with minimal BufferBloat.
At 16 threads, Stock configuration seem to max out around 550Mbps with minimal BufferBloat.
At 16 threads, Hardware Acceleration configuration seem to max out around 650Mbps with bad buffer bloat. (DSL Reports)
Speedtest.net puts hardware acceleration at 900Mbps+

Here is the info and tests you were looking for:

Now running the "stock" OpenWRT with out any SQM

16-threads, NO hardware acceleration, NO SQM
http://www.dslreports.com/speedtest/44441698
16-threads, WITH hardware acceleration, NO SQM
http://www.dslreports.com/speedtest/44441763

My take away? If you are an internet connection that is 600Mbps, or less, just run the stock configuration and don't bother with hardware acceleration.

I would love to see someone, with more skills than I, start up a performance tuning thread for the ERX.
