budgetvm-128m内存openvz VPS测评-欧站网

白天的chinaz的ping，结果如下：

做个参考，探针上面的：

E5的大母鸡啊，128M这款内存的VPS就给了1核：

power management:

128M内存有点小？没关系这不是有256M内存的swap么？

10G硬盘配这128M内存也不少：
root@zhujiceping:~# df -lh
Filesystem Size Used Avail Use% Mounted on
/dev/simfs 10G 1.2G 8.9G 12% /
none 64M 4.0K 64M 1% /dev

none 5.0M 0 5.0M 0% /run/lock
none 77M 0 77M 0% /run/shm
none 100M 0 100M 0% /run/user

这也是个G口：

试试从我自己的digitalocean的VPS上拉文件：
root@zhujiceping:~# wget http://192.241.222.161:8910/lnmp1.0-full.tar.gz

DD看看，VZ一般在100MB/s以上我就满意了，不要求别的
root@zhujiceping:~# dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync
16384+0 records in
16384+0 records out

再次验证一下网络和I/O，结果与前面的wget下载以及DD没啥差距，基本稳定：
