servgrid-VPS云简单测评(512m内存)

We bought a servgrid cloud VPS, 512M memory based on KVM VPS, 10G SSD hard drive, 1T monthly traffic, costing 5 US dollars (obtained from the official discount). Below I simply give some data, hoping to be a simple reference for friends who want to buy servgrid later!

Actually, I wanted to DD, but I found that the SSD command showed that it couldn’t be used, so I didn’t bother with it. root@zhujiceping:~# dd if=/dev/zero of=test bs=512k count=4k oflag=dsync 4096+0 records in 4096+0 records out 2147483648 bytes (2.1 GB) copied, 41.6037 s, 51.6 MB/s
