如果你需要的话，Linux Sysbench的二进制版本在这里：
Sysbench-0.4.13-lux86
Sysbench-0.4.8-lux86
使用UNIX socket来运行Point-Selects测试的Sysbench命令如下（在parallel中启动8个进程）：
LD_PRELOAD=/usr/lib64/libjemalloc.so /BMK/sysbench-0.4.8 --num-threads=$1 --test=oltp --oltp-table-size=10000000
--oltp-dist-type=uniform --oltp-table-name=sbtest_10M_$n
--max-requests=0 --max-time=$2 --mysql-socket=/SSD_raid0/mysql.sock
--mysql-user=dim --mysql-password=dim --mysql-db=sysbench
--mysql-table-engine=INNODB --db-driver=mysql
--oltp-point-selects=1 --oltp-simple-ranges=0 --oltp-sum-ranges=0
--oltp-order-ranges=0 --oltp-distinct-ranges=0 --oltp-skip-trx=on
--oltp-read-only=on run > /tmp/test_$n.log &
