They both share the same code base and I doubt very much the time telling ability of either differs. It's not like they're going to do if(IsClientVersion) { SkewTimeSlightly(); } else { SuperAccurateTime(); } ! –  Ben Pilbrow Aug 3 '11 at 20:17

Specify "time critical". Do you mean "real time"? Then Windows is not a real time OS. In this case you need an OS designed for that purpose. RTLinux for example. And your software must also be designed for real time. So what software is it? –  mailq Aug 3 '11 at 20:20

@Ben: That is not correct. Windows Server OSes do implement different scheduling algorithms than Desktop OSes. Servers prefer background processes than foreground processes. –  mailq Aug 3 '11 at 20:25

@mailq That's only partly true. It's a matter of default settings, which can be changed. sysdm.cpl->advanced->(Performance)Settings...->Advanced –  84104 Aug 3 '11 at 21:28

@Jonathan - People are downvoting because, as the FAQ states, this site if for PROFESSIONAL sysadmins, and even considering using W7 in a production environment as a server is considered unprofessional by professional sysadmins. –  Chopper3 Sep 22 '11 at 14:44
