I'm hoping I'll have the opportunity to build a similar machine soon and am wondering about the choice of 64 bit distributions. Gentoo is obviously a possibility but I'm also condsidering Debian. There is also a 64 compile of redhat sources somewhere around, but I can't remember what they call it offhand. If anyone has opinions about that, I'd be happy to hear. regards Iain ----- Original Message ----- From: "Daniel Ceregatti" <daniel@omnis.com> To: "Merlin Moncure" <merlin.moncure@rcsonline.com> Cc: <pgsql-performance@postgresql.org> Sent: Saturday, November 06, 2004 3:23 AM Subject: Re: [PERFORM] postgresql amd-64 >I have two dual opteron 248's with 4g of ram each, 6x36G 15k rpm ultra > 320 scsi disks in hardware raid 5, and they are by far the fastest > machines I've user used.
