All of them have poor disk write speed. Performance from 12MBps - 25MBps. I tried it on other servers but the performance is the same. Latest Debian stable on the same machine have 300MBps disk speed. Am I missing something after installation or this is the default speed? -- Marko Lerota Sent from my GNU Emacs/Gnus Mailer
