score for RapidXen 6/10 xen 2.6.32.12-RX-domU-static Los Angeles, California

結論

網路只有 ping 直到台灣不錯，下載速度並不快 (所以選在LA或是美西的VPS都不錯，延遲時間很短 )
network speed to taiwan, sucks 0
disk read performance, sucks 0
cpu performace, OK 1
service, sucks 0

You just skip this provider to save your time and money.

2010-07-14 09:00 買了 RapidXen
2010-07-14 11:00 在IRC 上面問怎麼沒有開通的 email 通知，客服說要 724 小時才會處理好，美國真是人性化，不願意自動化，才會有工作機會
2010-07-15 08:14 接近24 小時，過去了，沒有任何通知信，目前的感覺，這一家也不是什麼好貨色，爛到爆，2010 年了，還有這樣人力開通的，在IRC 上面問，怎麼這麼慢？，他們說，他們要避免濫用，還註冊的攻擊，另一點就是會 hold chinese order，但是我等了24小時，在 IRC 上面問，問為什麼還沒有記資料來，抱怨沒有開通，所以又進入了懲罰清單 penalty list，會等更久，果然令人想罵髒話，customer service sucks, If you complain more they will keep you wait longer, make you feel sucks more.

2010-07-15 17:04 原來有人抱怨，還等了三天，只是，他會把你踢出來，不給你買，哇，真跩，第一次看到這樣做生意的，超過24小不理你，還怪你抱怨他慢，然後就是 Chinese 該死，要等更久，我一定要試試，一定把數據記下來，看到底值不值接受這樣客服 http://www.webhostingtalk.com/showthread.php?t=934659&highlight=RapidXen

2010-07-16 11:04 一樣，沒有消息，基本上可以不用是這一家了，就算打折過後，也不會比 Linode 便宜，選他不如直接用 Linode 就好了

2010-07-16 17:53 通了，測試中

PS: 這一系列的 VPS 文章，就到我找到好又便宜的，就不寫了，基本上，怎麼選才能找到好的供應商呢？基本的原則，就是他的 VPS node 都賣光光，就是好的

是一家在德國，及美國都有資料中心的 VPS 供應商

我用的是在德國法蘭克福的 XEN 512 plan ，一個月大約 7.9 美元，缺點是網路有時慢一點，還有網路節點太多了點，到台灣接近要跳 28 個節點，這一個問題，說起來要怪台灣自己沒有什麼網路建設，連到歐洲，還要先連到美國，利用美國的網路連歐洲，就是自己網路建設擺爛，也怪不了別人，由中國連應該會好一點，目前沒有提供 32 bit 的作業系統

就差網路節點有點多了，最佳 CP 值很有機會，cpu 還是 i7 的，最後不知道是不是他

I tried, comes the result.

千萬不要用這一家，最近在各個地方發折價的消息，嚴重超買 oversold ，我買的 512 plan，在完全沒有 覆載下測試，原本只是效能差，現在連 Disk IO sucks 都跟著爛掉了，

DamnVPS just make you feel worse than damn it.

XEN RAM 512 PV，and this plan only get one virtual core, the 1G plan get 2 virtual core

VPS 甘苦談

2host 便宜，穩定，可是超賣，效能到了美國上班時間，就會慢下來，網路速度不錯

HazeNET 便宜，效能最好，網路速度不錯，可是一天當機好幾次，我的 VPS 現在還是離線中

Thrust::VPS 便宜，網路速度不錯，可是機車的是 512 RAM 的 node 限制只有一顆 CPU，網路上別人說，unixbench 4.1 跑起來，沒有 200 分的可以丟了，他不到 100 分，不超賣，也不會給你用壓，用了幾天，還蠻穩定的，跟 2host 比起來，算是比較有人管，網路速度，也不錯，分數不高，算是便宜穩定的

ramhost 口碑不錯，可是機車，已經沒有了空的 node 了

Linode 口碑很好，可是價錢很硬，即使很多空的 node 賣不掉，就是不降價

結論就是，2host 加減用，有好的，評估一段時間在跳了，還好，我的系統，整理的ok，搬家打不到幾行指令就搞定

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

FINAL SCORE 181.0


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

看到新聞，政府做做樣子符合一下百姓的期待，配合一下

打得不痛不癢，當然假打房，貸款利率，還有成數，投資客拿得本來就不比一般民眾差了，所以等於沒打

有一天，當政府跳出來說，要是成交價課稅的時候，才是玩真的，其他都只是做做樣子，讓老百姓開心的
