The CPU is a quad-core with Hyperthreading, thus appears to the operating system like having 8 cores. The configuration of our machines (with MSI X58 Pro motherboard, 6 GB memory, large disk, and a cheap NVidia graphics card) was established at http://www.hardwareversand.de (I'm not affiliated with this company but I bought my son's PC there, and he's happy with it). The price of such a machine is slightly below 1000,-€, including sales tax and 20,-€ cost for putting the pieces together. | The CPU is a quad-core with Hyperthreading, thus appears to the operating system like having 8 cores.

The BIOS has lots of things that one can adjust; at least the IDE mode should be set to AHCI and the C-states activated. After installing the 64bit version of CentOS 5.2 from DVD we discovered that the RTL8111C network adapter is not well supported by the slightly old installation kernel. So we downloaded (from a different machine ...) one of the kernel (plus kernel-devel and kernel-headers) RPM packages from the site http://people | The BIOS has lots of things that one can adjust; at least the IDE mode should be set to AHCI and the C-states activated.

So we downloaded (from a different machine ...) one of the kernel (plus kernel-devel and kernel-headers) RPM packages from the site http://people.redhat.com/dzickus (at least version 128) and installed those with the help of a USB stick (we also needed the --nodeps option). | ||
'''Update''': NFS under the -128 kernel does not work well under high load. But there are RTL8111C drivers available at [http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=2&PNid=13&PFid=5&Level=5&Conn=4&DownTypeID=3&GetDown=false#2] which I will try. | '''Update''': NFS under the -128 kernel does not work well under high load.

'''Update 2''': Never got around to trying them but my self-compiled 2.6.27.x kernels work well. | |||
