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

基本上，我試過的每一家，網路都比 RapidXen 快， NordicVPS 有時候比 2HOST 快，不過他的機房比較遠

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
