前段时间发现在阿里云ECS搭建mysql和本地mysql同样的查询 发现读取性能远远不如本地机械磁盘
于是今天做了一个阿里云高效云盘的读写和本地磁盘读写性能对比
阿里云高效云盘读取效率
[email protected]:~# hdparm -tT /dev/vda1
/dev/vda1:
Timing cached reads: 14732 MB in 2.00 seconds = 7380.98 MB/sec
Timing buffered disk reads: 410 MB in 3.01 seconds = 136.05 MB/sec
[email protected]:~# hdparm -tT /dev/vda1
/dev/vda1:
Timing cached reads: 16142 MB in 2.00 seconds = 8089.48 MB/sec
Timing buffered disk reads: 428 MB in 3.01 seconds = 142.27 MB/sec
[email protected]:~# hdparm -tT /dev/vda1
/dev/vda1:
Timing cached reads: 16242 MB in 2.00 seconds = 8138.87 MB/sec
Timing buffered disk reads: 412 MB in 3.00 seconds = 137.21 MB/sec 本地机械磁盘读取效率
[[email protected] config]# hdparm -tT /dev/sda1
/dev/sda1:
Timing cached reads: 15764 MB in 2.00 seconds = 7900.86 MB/sec
Timing buffered disk reads: 1024 MB in 1.28 seconds = 798.49 MB/sec
[[email protected] config]# hdparm -tT /dev/sda1
/dev/sda1:
Timing cached reads: 16106 MB in 1.99 seconds = 8073.20 MB/sec
Timing buffered disk reads: 1024 MB in 1.27 seconds = 807.60 MB/sec
[[email protected] config]# hdparm -tT /dev/sda1
/dev/sda1:
Timing cached reads: 15582 MB in 1.99 seconds = 7811.29 MB/sec
Timing buffered disk reads: 1024 MB in 1.34 seconds = 765.92 MB/sec这就是阿里云高效云盘的读取结果
以后还是买阿里云的ssd的磁盘把 高效云盘有点搞笑呀
