I'm currently looking =20 at two Supermicro based options, one with a Core 2 Duo Q6600 Quadcore =20= 2.4GHz 2x4MB (on a PDSMi+ board) , and another with two Xeon 5110 =20 dualcore 1.6GHz 4MB (on a X7DVL-i board). Both configurations would have 4GB (2x2Gb) memory (to begin with, 4 =20 slots on the boards so max 8GB), and I'm thinking about 4x 500GB =20 disks in a raid10 config on a 3Ware 9550SX. What my question is, from the performance point of view, what would =20 be best? Two dualcores or a single quadcore? I'm thinking about =20 memory bandwidth and such... Bus bandwitdh (to ethernet and disks)... Looking from the upgrade point of view I guess two dualcores can be =20 replaced with two quadcores, but on the other hand, if that will be =20 necessary then another box is probably a better solution... Is there any known problems with FreeBSD and these stuff? =46rom what =20= I've understood Supermicro is pretty FreeBSD-friendly and should work =20= fine... The box will be used mainly with a jail running MySQL and Apache 2, =20 and a number of other jails which will take fare less power... So =20 mainly mysql & apache. If someone have any clues about which system performs best, or any =20 other input, everything is appreciated! Thanks -- Johan Str=F6m Stromnet johan@stromnet.se http://www.stromnet.se/
