I just re-ran a test at aql_txq_limit
= 1500 with WED enabled and then again with WED disabled:
aql_txq_limit 1500
+ WED Enabled:
aql_txq_limit 1500
+ WED Disabled:
There is undoubtedly much tighter control on latency with WED disabled--far fewer excursions from a baseline, though still more excursions into higher latency than I would prefer to see.
