I did a few benchmarks after installing OpenWrt:
SNAPSHOT r27119-c609c3bd6e
Raw networking performance: ~750 Mbps
iperf3 from x86_64 desktop to server on gnubee
SATA disk benchmarks (a single device at a time)
TEST_DIR=/mnt/tmp
SIZE=1G
IODEPTH=16
RUNTIME=30s
PARAMS="--directory=$TEST_DIR --size=$SIZE --iodepth=$IODEPTH --time_based --runtime=$RUNTIME --ramp_time=2s --direct=1 --verify=0 --ioengine=libaio --group_reporting=1"
