> Sub-millisecond latency variations are quite normal. Does anybody still
have any issues relevant to this ticket, or can it be closed?
I didn't require QoS and I wasn't using QoS before these patches. Post-
patch, it seems QoS is absolutely necessary and it's still unable to
restore performance to previous levels.
I wasn't getting dropped packets and overruns before. I've tried
decreasing the tx ring size from 48 to 32, but that didn't seem to help
either.
Ping replies are slightly more stable than with the previous broken patch,
but they're still worse than before any of these patches.
I'm seeing dropped packets on the WAN and LAN interfaces, but they're not
increasing. The dropped packets are probably not a big deal, but they
might indicate there's a subtle problem.
This is what kind of latency I was getting, sorted from the lowest latency
to greatest:
before patching < current post-patch < previous broken patch
These patches have increased download bandwidth by 10 mbps, but latency
has increased and this looks like bloated behavior.
I'm trying to find an alternative to ar71xx based hardware and replace
ar71xx.
