On continue avec un nouveau bench d'une machine OVH. Cette fois on va bencher la nouvelle BestOf qui est sortie en juillet 2013. Elle est un peu plus cher que la SP 32G mais elle bénéficie d'une vraie carte RAID ce qui améliore grandement les performances disques. Ce sont d'ailleurs les mêmes disques SATA que dans la machine SP32G. Par contre le processeur est un peu moins bien que sur l'ancien modèle même si il s'agit d'un Xeon i7. Celui-ci est un peu moins rapide que l'ancien modèle sur sysbench. Elle est proposée à un tarif de 59.99€ HT/Mois. Dans ce benchmark nous allons utiliser deux kernels différents. Un kernel de la branche 3.2 et un kernel de la branche 3.8 (Kernel OVH par défaut).
Caractéristiques techniques et informations supplémentaires
- OS : Debian Squeeze, kernel debian 3.2.0-0.bpo.4-amd64
- Disque : TOSHIBA DT01ACA200 (2 disques)
- Raid : Raid1 sur carte Intel RS25AB080
- CPU : Intel(R) Xeon(R) CPU W3530 @ 2.80GHz
- RAM : 32Go
