RE: difference on linux advanced server...




Hello,

Is this distribution also available by download ?
I've checked their ftp server, but I only see the SRPMS.

I would like to test it before choosing or not to pay for it.

Thanks for any responses,
Christophe

>|
>|  a.. Asynchronous I/O support: Applications no longer need
