[LEDE-DEV] WRT1900ACS Testing

Fri May 20 14:16:13 PDT 2016

We had found some pretty major performance problems on this hardware
as of a few months ago. I am curious if they still exist? A whole
bunch of benchmarks went by on the cerowrt-devel list, also.

They were:

1) broken local ethernet network stack - running 4 copies of netperf
against it - one would grab all the bandwidth and the other three
barely even start or hang completely.

2) No BQL in the ethernet driver

3) Wifi was horribly overbuffered in general

4) Wifi would crash against flent's rrul test.
