crowncloud-简单测评

We bought a crowncloud VPS [crowncloud-2g memory KVM/8 cores/30g hard drive/3T traffic/monthly payment of 7 US dollars] the day before yesterday. We will briefly review it and hope to provide guidance to friends who plan to buy it. The specific server is in the webnx computer room in Los Angeles. Each VPS is 100M shared. CPU model [8 cores] QEMU Virtual CPU version (cpu64-rhel6) | Frequency: 2400.084 | Level 2 cache: 4096 KB | Bogomips: 4800.16 × 8.
