天翼云啊，你妹！

I got Tianyi Cloud from Mumao, the 1G memory model. The promotional price is 52 RMB per month if you pay annually. After getting it, I played with the hardware and it looks very powerful. However, the hard disk data is a bit tragic. I guess more people will play with it. The download speed of cachefly is about 1.7M per second (Hong Kong node), and the download speed of the United States is only more than 20K per second. It hurts. Telecom line access is very powerful. China Unicom access is similar to oneasiahost in Singapore from mainland China. To put it simply, it is still possible to build a website, but if it is not correct, it can only face customers in mainland China. root@localhost:~# cat /proc/cpuinfo processor: 0 vendor_id: GenuineIntel cpu family: 6 model: 47 model name: Intel(R) Xeon(R) CPU E7- 4830 @ 2.13GHz stepping : 2 microcode: 0x36 CPU MHz: 2131.022 cache size: 24576 KB fpu:yes fpu_exception: yes cpuid level: 11 wp:yes flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts mmx fxsr sse sse2 ss syscall nx rdtscp lm constant_tsc up arch_perfmon pebs bts nopl xtopology tsc_reliable nonstop_tsc aperfmperf pni pclmulqdq ssse3 cx16 sse4_1 sse4_2 x2apic popcnt aes hypervisor lahf_lm ida arat epb dtherm bogomips : 4262.04 clflush size: 64 cache_alignment: 64 address sizes: 40 bits physical, 48 bits virtual power management:
