So I'm stuck running it on Because new ones no longer exist and new AMD64 hardware easily beats alpha or SPARC hardware, with SPARC T3 being only serious competitor in total throughput, but with enormous price and being in hands of oracle. > AMD64. Nothing against AMD, they did what they could to try and make a silk AMD64 is instruction set standard, made first by AMD but now all intels have it too. > a high quality board in amd64/x86 land with good reviews doesn't compare. i would say that Dell servers are actually good in compatibility with standards and performance. the "low end" (single socket xeon) ones are cheap, others are not. > The firmware is absolute crap, and it's not like it is something you can true. > >> Performance has been degraded by a whopping 75% ! > > Having a 4KiB misalignment is nothing compared with not having NCQ 4kB misalignment is HUGE performance loss. > Speaking of alignment, I still get "partition 1 does not end on a so why you create windows style slices at all?
