真是天下最大的笑話，由國外，下載國內的 FTP 站的速度，比我們的種花電信，還要快

說什麼發展數位內容，雲端技術，光是網路建設不進步，只知道壟斷，吸老百姓的鈔票，真不知道要發展什麼

買了新的 VPS

RAM 1024 MB，OpenVN，現在 40% OFF，花了 8.4 USD，真是超值，網路實測，封包不掉，到台灣學術往錄下載 ISO 檔，2host 因為是沒有限速，可以跑到1~3M之間網路速度，2host 算是大勝，因為 10TB ，幾乎算是不限頻寬， HazeNet 的VPS 大約在 600 KB/s 左右，跟我選的規格上面限速的差不多，他可以選，UNMETERED 5mbit，或是 500GB @ 50mbit，我暫時還是跑不限流量的，在 SolusVM 的管理介面裡，所有的資訊都會跟 VPS 的狀態同步，資訊比 2host 的圖表資料多，不過接下來，就看穩定性，還有看他們會不會跑路了

PS: 分數不代表一切，也不代表，效能你可以全用，不過爽度也蠻重要的，HazeNet 算是非常新的 VPS，可能等他一切都穩定了才知道，到底行不行，我三天，被換了，兩個 IP，老闆說，他放在 isp 的 server 出了點問題，所以現在是 offline 的

一開始使用時候，做一些壓力測試分數不算是突出的 VPS，可是實際使用起來，穩定性還不錯，網路連美國本土，還有台灣速度都還不錯，頻寬一個月10T 幾乎是無限使用，我根本用不完，網站跑起來，速度一點也不輸給，原本放在種花電信的速度，所以開始不用把 server 再放在自己家中，雖然管起來也很輕鬆，不過，要響應節能減碳，既然，自己的 server 用電一個月都花得比買 VPS 還貴，乾脆就用 VPS 吧，目前用一個星期來，很滿意，除了，有一次，我跑壓力測試，測的太兇，把 512 MB 的記憶體，還有 1G 的 SWAP 吃光光，機器自己 reboot 外，目前用起來，還蠻穩定的，跑兩個站，用 Django跑 fastcgi 再 nginx 後面，吃不到 200 MB （32 bit OS 可以吃更少），不過提供的 kernel 有點舊了，我用的是 Debian 2.6.18-164.15.1.el5xen，server 穩定就好了，也不必一昧的追新，這是使用一個星期的感想

這一星期，一直在比其他 VPS 的穩定性， unixbench 分數，還有就是網友的口碑，最好的是 Linode 不過價格就很硬了，現在記憶 512 MB的方案 19.95 元美金，和 2host 7.99 元美金貴了很多，雖然硬碟空間，還有 unixbench 及 redis-benchmark 的分數比較高，不過便宜是王，只要穩定性不差，就好了，另一家是 ramhost 口碑不錯，資訊很公開，有實際每一台主機的狀態，算是沒有超賣有口碑的 VPS 供應商，不過他是 OpenVZ 的我比較不喜歡，還是喜歡 Xen 的 VPS，資源分的比較乾淨，所以這完全是對個人口味的選擇。

另一點重要的是，他提供的價錢很迷人，頻寬很大，所以定期的備份是一定的，怕哪一天他跑路，這是不管用哪一家都必須注意的問題

再穩穩跑一陣子，以他連美國本土的速度優勢，程式交易，下美國的商品，應該延遲就可以贏很大了


最後說說缺點

管理介面的數值報表幾乎沒有，

硬碟空間，我選的 512 MB 的這一個方案只有 10G 的硬碟空間，Debian 只有 64 bit 可以選



還有更便宜的，像是新公司 http://hazenet.co.uk/

2010-06-29 更正，實際分數跑起來，不算高，我問問看客服，有沒有官方的數據可以比較，還是要多比較一下，我會再看看 Linode 的

便宜又大碗，先用用看，目前還蠻穩定的，連台灣，網路還算 OK

我是選 512M的 VPS 一個月 8 塊美金左右，大概比我自己擺 server 的電費還省，下面是 CPU info 可以參考一下，不過，我自己跑起來實測，有比 Amazon em2 的最便宜的 small instance 大約快兩倍，不過就比不過 middle 的了，如果有問題就發問吧

跑了 nginx，mysql ，兩個 Django site 大概用了 150M RAM
