主机测评在8月9日晚十一点做买了一款bandwagonhost的VPS，想把这款VPS的一些数据分享给大家，于是就随性想到哪里就写到哪里,有兴趣的凑合着看！先说下这款VPS的参数：基于openvz(2代)，512M保障内存，512M vswap，5G硬盘，带宽这个有讲究(incoming：1G，out:100M),CPU默认说的是给1core但是你拿到手后会发现实则是2core（Intel(R) Xeon(R) CPU L5520 @ 2.27GHz | 频率:1134.000 | 二级缓存:8192 KB | Bogomips:4533.95 ×2）。 [bandwagonhost-512m内存/5g硬盘/500g流量/年付9.99美元 ]
