Kai Shen 79a22238b4 net/smc: Use percpu ref for wr tx reference ... The refcount wr_tx_refcnt may cause cache thrashing problems among cores and we can use percpu ref to mitigate this issue here. We gain some performance improvement with percpu ref here on our customized smc-r verion. Applying cache alignment may also mitigate this problem but it seem more reasonable to use percpu ref here. We can also replace wr_reg_refcnt with one percpu reference like wr_tx_refcnt. redis-benchmark on smc-r with atomic wr_tx_refcnt: SET: 525707.06 requests per second, p50=0.087 msec GET: 554877.38 requests per second, p50=0.087 msec redis-benchmark on the percpu_ref version: SET: 540482.06 requests per second, p50=0.087 msec GET: 570711.12 requests per second, p50=0.079 msec Cases are like "redis-benchmark -h x.x.x.x -q -t set,get -P 1 -n 5000000 -c 50 -d 10 --threads 4".
