lfcvps 1G/XEN evaluation

LFCVPS simply released a promotion on LET. XEN with 1G of memory only costs $6.50. This was really unsettling, so I bought it and paid for it in one month. I have bought a LFCVPS 256 memory before and reviewed it before (https:// /lfcvps-ceping/). Now I will simply release the review of this 1G memory VPS. For details about the parameters of the lfcvps server and the introduction of LFCVPS, please check https :// /lfcvps/ CPU: root@x:~# cat /proc/cpuinfo processor: 0 vendor_id: GenuineIntel cpu family: 6 model: 45 model name: Intel(R) Xeon(R) CPU E5-2620 0 @ 2.00GHz stepping : 7 CPU MHz: 1999.999 cache size: 15360 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu: yes fpu_exception: yes cpuid level: 13 wp: yes flags: fpu de tsc msr pae cx8 sep cmov pat clflush mmx fxsr sse sse2 ss ht nx constant_tsc nonstop_tsc pni pclmulqdq ssse3 sse4_1 sse4_2 x2apic popcnt aes avx hypervisor bogomips : 3999.99 clflush size: 64 cache_alignment: 64 address sizes: 46 bits physical, 48 bits virtual power management: Processor: 1 vendor_id: GenuineIntel cpu family: 6 model: 45 model name: Intel(R) Xeon(R) CPU E5-2620 0 @ 2.00GHz stepping : 7 CPU MHz: 1999.999 cache size: 15360 KB fdiv_bug :no hlt_bug : no f00f_bug : no coma_bug : no fpu: yes fpu_exception: yes cpuid level: 13 wp: yes flags: fpu de tsc msr pae cx8 sep cmov pat clflush mmx fxsr sse sse2 ss ht nx constant_tsc nonstop_tsc pni pclmulqdq ssse3 sse4_1 sse4_2 x2apic popcnt aes avx hypervisor bogomips : 3999.99 clflush size: 64 cache_alignment: 64 address sizes: 46 bits physical, 48 bits virtual power management:
