以前没有用过NVME,这次的OVH的服务器的SSD是NVME的,赶紧装个VM测试下IO
测试所使用的程序:
wget -qO- bench.sh | bash
下面是结果:
---------------------------------------------------------------------- CPU model : Intel(R) Xeon(R) E-2236 CPU @ 3.40GHz Number of cores : 8 CPU frequency : 3407.998 MHz Total size of Disk : 22.3 GB (1.8 GB Used) Total amount of Mem : 7987 MB (183 MB Used) Total amount of Swap : 7628 MB (0 MB Used) System uptime : 0 days, 3 hour 40 min Load average : 0.00, 0.00, 0.00 OS : Debian GNU/Linux 9 Arch : x86_64 (64 Bit) Kernel : 4.9.0-12-amd64 ---------------------------------------------------------------------- I/O speed(1st run) : 1.3 GB/s I/O speed(2nd run) : 1.3 GB/s I/O speed(3rd run) : 1.3 GB/s Average I/O speed : 1331.2 MB/s ---------------------------------------------------------------------- Node Name IPv4 address Download Speed CacheFly 205.234.175.175 114MB/s Linode, Tokyo2, JP 139.162.65.37 9.46MB/s
可以看到,IO读写能够到1.3GB/s…比sata ssd 要快1倍,这是很爽的
