DigitalOcean UnixBench跑分很不错

前两天用DigitalOcean的优惠码购买了一个512MB内存的VPS,今天做了一个跑分测试,性能很不错,达到了1414.8分,带宽、I/O也很不错,看来固态硬盘对性能的提升还是很明显的,下载速度可以达到84.3MB/s。

提示:虽然机器的网速很不错,但是由于测试的下载文件在国外,从国内访问的速度还有待考验,我下载一个测试文件,发现速度不如MediaTemple给力,当然这个情况跟路由有关系。

MediaTemple的GS一对比,发现差距还是蛮大的,特别是下载速度和I/O,MediaTemple采用的是存储,在稳定性上应该更胜一筹,DigitalOcean采用的是本机的SSD,在速度上优势明显。

如果你的访客主要在米国,在选择VPS的时候可以考虑DigitalOcean,毕竟性能不错,并且价格还挺实惠。网上有不少评论说如果不符合他的TOS会被关闭账户,这点大家也要留意一下,如果违反他们的TOS的话,还是选择其他VPS,以免造成不必要的麻烦。
