Doesn't CONFIG_PREEMPT will add userspace scheduling overhead which in turn harm kernelspace workloads such as packet routing, firewalling, NAT, etc.? I had done some tests in the past with the scheduling priority of the hostapd daemon (with nice and schedtools) but never spot a gain in bandwith or latency with iperf. - Otto _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
