I agree with you Frank, but if we are talking about Standard and recommendations I will follow Redhat Regards Samer Azmy <div>On 10/17/07, Lamon, Frank III <<a href="mailto:Frank_LaMon@csx.com">Frank_LaMon@csx.com</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Do not waste disk space with 64GB of swap! If you are using 64GB of swap you need to buy more RAM. Depending on the app the use of swap could absolutely kill your performance or even app stability (think Oracle). 8-16GB of swap would be more than enough. -----Original Message----- From: <a href="mailto:rhn-users-bounces@redhat.com">rhn-users-bounces@redhat.com</a> on behalf of Samer Azmy Sent: Wed 10/17/2007 2:41 PM To: Discussions about Red Hat Network ( <a href="http://rhn.redhat.com">rhn.redhat.com</a>) Subject: Re: [rhn-users] RHEL5 Ram and Disk Partiton Gentlemen, for the Size of the SWAP it should be double the RAM Quoted from Redhat site "A swap partition (at least 32MB) - swap partitions are used to support virtual memory. In other words, data is written to a swap partition when there is not enough RAM to store the data your system is processing. The size of your swap partition should be equal to twice your computer's RAM, or 32MB, whichever amount is larger."
