RamNode 4GB VDS 評測

RamNode 在 3/16 日大幅調整 OpenVZ / KVM 標準款的售價，價格降下來與 Linode 和 Vultr 同級 VPS 相同了，並推出新的 VDS KVM 主機，真正獨立 CPU，價格略高一點。

VDS KVM SSD 的規格

Plan: 4GB SVDS
RAM: 4096MB
CPU: 1 Dedicated Core
IPv4: 1
IPv6: /64
Storage: 100 GB
Bandwidth: 5000 GB
Price: $20 / mo

目前 RamNode LA 機房缺貨，站長只能先買 SEA 西雅圖機房的來測試，整體效能不錯，等到 LA 有貨時，再換過去。

CPU E3-1240 v3 算是主流了，主頻 3.40GHz，硬碟 SSD I/O 高的嚇人，莫非有做 cache

西雅圖機房到台灣的網路 ping 值，平均 155 ms

對大陸網路的 ping 值就差點，還是 LA 機房會好一點

主機本身的下載 / 上傳 速度：

很久沒做主機性能測試了，看一下 CPU 獨立核心的效能：

站長已經好久沒看到 CPU 和 SSD I/O 性能這麼優的主機，RamNode 用這方案價格跳脫現在廝殺慘烈的 1GB / 2GB VPS 市場，也算是不錯的策略，至少比 Vultr VDS 便宜不少，就等 LA 機房的 VDS 鋪貨，對台灣和中國的網路品質會好很多。
