Richly deserved IMNSHO. my current employer was bilked for many many months for a piece of crap E10K that barely outperforms a couple of AMD chips. But at many, many times the price. We finally upgraded/migrated to AIX/g5 chips and run what was run on 20 cpus on 2. If Sun pulls out of its slow Icarus dive to near-certain death, it'll be a miracle. ( And, I guess, that'd be "a good thing"; always nice to have a miracle. ) -----Original Message----- From: pgsql-general-owner@xxxxxxxxxxxxxx [mailto:pgsql-general-owner@xxxxxxxxxxxxxx] On Behalf Of Richard_D_Levine@xxxxxxxxxxxx Sent: Tuesday, April 26, 2005 3:12 PM To: mmiranda@xxxxxxxxxxxxxxxxx Cc: pgsql-general@xxxxxxxxxxxxxx; pgsql-general-owner@xxxxxxxxxxxxxx Subject: Re: UltraSPARC versus AMD Sun's stock was at $65.00 in late 2000 and has rocketed to $3.50.
