Irony is as follows, Linux is mounted async by default and their babbling about it's speed in email, but once linux crashes, you could say byebye mail queue! ----- Original Message ----- From: "Brad Knowles" To: "Giorgos Keramidas" ; "Jonathan Fortin" Cc: Sent: Wednesday, June 13, 2001 7:10 PM Subject: Re: Sysadmin Article --Which OS is Fastest for High-Performance Network Applications? > At 11:26 PM +0300 6/13/01, Giorgos Keramidas wrote: > > > o I am not sure if you do have an option in linux to mount > > filesystems with synchronous writes. > > Yes, Linux does have this option.
