This will re-enable the so called "early drop hack" that checks early in the output path whether or not there is room left in the interface queue. This reduces the workload and the network lock contention as it avoids unnecessary progressing of packets that can't be queued (and later sent out) anyway. For ALTQ enabled queues the check is disabled. Before this change it was disabled for *all* queues once you put in "options ALTQ". > Max Laier wrote: > >Hi, > > > >I'd like to merge the following diff to RELENG_5 in order to gain > > performance for the most common ALTQ setups (huge, unALTQed LAN-if and > > small(er), ALTQed WAN-uplink).
