digitalocean kvm vps简单测评(512M旧金山)

The digitalocean VPS I just bought is based on KVM. The San Francisco data center is very friendly to mainland China. China Telecom and China Unicom are directly connected. I simply checked the parameters of the VPS and found that the CPU is virtualized. The 2G frequency limit is enough for building a website. The wget download seems to have a G port. The one-click backup tool in the background is very simple. If data is lost, it can be restored with one click. Official website: www.digitalocean.com Post it and mess with it later:

As far as I know, Chinese people attach great importance to ping (the picture below is the ping test of the San Francisco VPS we purchased):

————————————————————– We attach great importance to downloading. The standard for testing bandwidth is almost G port: take a look at my 6M Guangzhou Unicom download test:

As for the CPU, it must have been virtualized based on the KVM pit, but given the main frequency of 2299Mhz, I think it is more than enough to build a website! root@hello:~# cat /proc/cpuinfo processor: 0 vendor_id: GenuineIntel cpu family: 6 model: 2 model name: QEMU Virtual CPU version 1.2.0 stepping : 3 microcode: 0x1 CPU MHz: 2299.998 cache size: 4096 KB fdiv_bug :no hlt_bug :no f00f_bug : no coma_bug :no fpu: yes fpu_exception: yes cpuid level: 4 wp: yes flags: fpu de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pse36 clflush mmx fxsr sse sse2 syscall nx lm up pni vmx cx16 popcnt hypervisor lahf_lm bogomips : 4599.99 clflush size: 64 cache_alignment: 64 address sizes: 40 bits physical, 48 bits virtual power management: ———————————————————- There is nothing to say about the memory situation: root@hello:~# cat /proc/meminfo MemTotal: 514452 kB MemFree: 323520 kB Buffers: 20432 kB Cached: 148912 kB SwapCached: 0 kB Active: 92728 kB Inactive: 82948 kB Active(anon): 6348 kB Inactive(anon): 108 kB Active(file): 86380 kB Inactive(file): 82840 kB Unevictable: 0 kB Mlocked: 0 kB HighTotal: 0 kB HighFree: 0 kB LowTotal: 514452 kB LowFree: 323520 kB SwapTotal: 0 kB SwapFree: 0 kB Dirty: 0 kB Writeback: 0 kB AnonPages: 6344 kB Mapped: 6688 kB Shmem: 128 kB Slab: 10872 kB SReclaimable: 7404 kB SUnreclaim: 3468 kB KernelStack: 904 kB PageTables: 416 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 257224 kB Committed_AS: 58804 kB VmallocTotal: 509952 kB VmallocUsed: 1824 kB VmallocChunk: 507888 kB HardwareCorrupted: 0 kB AnonHugePages: 0 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB DirectMap4k: 30712 kB DirectMap2M: 493568 kB ———————————————————– Check the hard drive root@hello:~# df -lh Filesystem Size Used Avail Use% Mounted on rootfs 20G 854M 18G 5% / udev 10M 0 10M 0% /dev tmpfs 51M 124K 51M 1% /run /dev/disk/by-label/DOROOT 20G 854M 18G 5% / tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 101M 0 101M 0% /run/shm – Hard drive DD detection, root@hello:~# hdparm -t /dev/sda /dev/sda: Timing buffered disk reads: 964 MB in 3.00 seconds = 321.21 MB/sec
