TrueNas Core 当前基准测试指标
我在日常的使用中， 如果是连续的文件，我其实感受不到磁盘性能的问题，一直都很好， 如果是小文件随机就非常的折磨。 这让我意识到自己还没有对磁盘进行基准测试 ，记录如下：
TrueNAS 读取 和 写入的测试监控， 每次测试5mins，开始的时间是 9：55 ， 所有磁盘都有写入的原因是 ，fio 在创建测试文件来测试读取。
ada0 是一个 sata ssd。
ada1 和 ada2 是两个 hdd。
吞吐量：
IOPS：
读取测试
这个是符合预期的 read 的所有请求都来自于内存。

写入的测试结果看起来没有那么美好，感觉是psync的原因， 没过内存数据直接写入的机械硬盘，看起来这个速度有点差， 这个盘 6Gbps 的总线， 能达到 83.3MiB/s， 感觉还是有点儿问题， 这个性能不足应该来自蜗牛星际的 IO 板子可能不太行。
