FreeBSD 11-0-RC2 man 4 vale <snip> SYSCTL VARIABLES vale uses the following sysctl variables to control operation: dev.netmap.bridge The maximum number of packets processed internally in each iteration. Defaults to 1024, use lower values to trade latency with throughput. dev.netmap.verbose Set to non-zero values to enable in-kernel diagnostics. </snip> > sysctl -a | grep dev.netmap.bridge dev.netmap.bridge_batch: 1024
