DMIT的圣何塞VPS的路由目前已经变更为普通线路，没有优化。根据官方的说法是由于合同已经结束，DMIT将不再与中国联通AS4837进行合作，而且套餐名称也已经更名为SJC.T1。这里面的具体原因就不去深究了，对于客户来说，想买就买，不想买就换商家。这篇文章大鸟博客就来测评下目前的dmit圣何塞VPS，想了解的小伙伴可以围观。

3、系统信息
AMD EPYC 7443P 24-Core Processor，磁盘IO：450.3 MB/s，这里的机器其实并没有变化。
4、杂项测试
ChatGPT：可以解锁美区。
Tik Tok：见上图，可以解锁美区。
流媒体：
三网测试：晚高峰测试，1G带宽跑成了这样，很拉胯。白天在测试下看看会不会好一点。
全球部分节点测试：
亚洲部分节点测试：
iper3欧美节点测试：
磁盘FIO：
真实磁盘读写测试：根据经验，一般数据在 大于20MB/s 为合格，大于40MB/s 为普通，大于80MB/s 为优秀。
5、路由
电信回程：圣何塞中国电信节点，直连国内，走的是电信163骨干线路。普通直连，没有优化。

联通去程：联通骨干对接cogent，直连到圣何塞。
移动回程：telia对接移动cmi，直连。也就是从圣何塞的中国移动pop，直连回国。

移动去程：走的移动cmi，绕日本东京，之后走移动cmi到圣何塞。
6、ping
7、服务器带宽测试
1）服务器网络测速，江苏电信100M带宽，23点测试结果，仅供参考。
2）IPv4 下载测试，江苏电信100M带宽，23点测试结果，仅供参考。
8、服务器性能测试
1）CPU等性能简单测试：
2）Geekbench v5 CPU Benchmark：单核1139，见上图。这个CPU性能还是很狂暴的。
详细：https://browser.geekbench.com/v5/cpu/21185922
3）unixbench跑分：还在测试中。
9、最后
服务器性能，还是很不错的，特别是CPU很给力。
网络方面：之前是三网回程4837，目前是三网回程走各自的骨干直连回国。去程方面电信和联通依然是直连到圣何塞，移动绕日本。
根据官方的说法是SJC目前虽然没有针对中国大陆优化的网络，但商家正在与其他供应商积极联系。
