> 问题描述：
> 在8C32G（fit机器）相同的客户端配置，
> 对齐throughput(point/s) = 17358854.98，
> 普通序列throughput(point/s)=18952049.86
> 对齐慢约9%，且cpu使用率高。

> 测试步骤：
> 1. 机器信息
> iotdb 192.168.130.1 /data1/master_0421_8db8876
> bm 192.168.130.2 /data1/benchmark_v13
> 2. 参数配置
> iotdb
> MAX_HEAP_SIZE="20G"
> MAX_DIRECT_MEMORY_SIZE="6G"
> wal_dirs=/data2/wal,/data3/wal
> benchmark参数配置见附件
> 3. 启动测试
> 监控机器资源，记录测试结果，对比。
