本站上才发布maximumvps的文章不久（maximumvps-kvm全面上货,最低8.5美刀年付）我这里就自己买了个想做个评测发给大家看看，如实从节约的理念出发买了个64M内存的最便宜的。洛杉矶Data Center，系统里面里面有ISO和net-install版本的debian、centos等，但是没有我喜欢的minimal，全面的评价一下就是这价格还是可以了，建站没啥问题的，慢慢开始折腾吧：

内存情况：（等会让自己加点swap） root@debian:~# free -m total used free shared buffers cached Mem: 58 26 31 0 1 14 -/+ buffers/cache: 10 47 Swap: 112 0 112
看看CPU，其实官方公布了为Dual L5420 root@debian:~# cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 13 model name : QEMU Virtual CPU version (cpu64-rhel6) stepping : 3 cpu MHz : 2500.088 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 sep mtrr pge mca cmov pse36 clflush mmx fxsr sse sse2 syscall nx lm up

安装好系统后就这情况： root@debian:~# df -lh Filesystem Size Used Avail Use% Mounted on /dev/sda1 4.9G 506M 4.1G 11% / tmpfs 30M 0 30M 0% /lib/init/rw udev 25M 80K 25M 1% /dev tmpfs 30M 0 30M 0% /dev/shm
下载测试一把速度： root@debian:~# wget http://cachefly.cachefly.net/100mb.test --2014-02-16 03:59:24-- http://cachefly.cachefly.net/100mb.test Resolving cachefly.cachefly.net... 205.234.175.175 Connecting to cachefly.cachefly.net|205.234.175.175|:80... connected.
