about server/s

[gnoochi]

is it possible to have several servers running on the ONE machine?

if so, will it degrade the performance of the servers sharing that machine.

Sure, not just possible, but the usual case. This box runs sendmail, pop3, sshd, Apache, etc. Now, the performance hit is hard to analyze, without further data. These things mostly sleep, no cpu, until they are asked to do work. If everything gets hit at the same time, there will be a penalty. In my case, that just never happens, but, a really busy web server, or mail machine would be a very different story. HTH, Ray
