Subject: UNIX bench better on 2.2 than 2.4?
Date: Fri, 15 Mar 2002 08:52:02 +0100 [thread overview]
Message-ID: <3C91A822.7030304@linkvest.com> (raw)
Sorry, I forgot to give kernel versions...
Hi,
I ran UNIX bench on 4 of our machines. The results are below.
What is strange is that 2.2 makes better than 2.4! Is it a known fact?
And is the UNIX bench better with 2 CPU?
