昨天主机的测试结果:https://hostloc.com/thread-985644-1-1.html
只看 GB5,单核从 814 降到 714,降幅 12%。多核从 1514 降到 1257,降幅 17%。还好,打个普通 E3、E5 没有问题。
网络性能正常,主动限速了 10MB,而且是隧道过去的 OVH IP,比不了。
磁盘性能有点离谱,我又在主机上测了下:

和昨天测的一样,没有问题。
这样的话只能把性能归功于缓存了,虽然主机本身硬盘性能一般,但再开个虚拟机通过缓存得到的测试结果反而比主机更好。
所以结论一句话:使用支持嵌套虚拟化的 VPS 再开个虚拟机,完全可以用。
另外有个小惊喜,php-friends 德国机房到 OVH 德国只有 2-3ms,Contabo 和 Hetzner 都要 5-6ms,虽然对于做站来说并没有什么区别。 |
