Compiling the linux kernel is a fairly good benchmark. Especially since a lot of my day is spent compiling code and programming. So I decided to compile a stock PaysonLinux kernel (2.6.32.9) in various systems and compare compiling time. Here are the results in each of my systems: Machine Number One: HP Pavilion dv6000 (laptop) Windows XP SP3 3 GB DDR2 800 MHz Ram 2.4 GHz Core 2 Duo PaysonLinux installed in VirtualBox with a 20 GB hard drive image (not dynamic) Real 76m56.418s User 40m6.351s Sys 43m53.418s Machine Number Two: Dell Optiplex (server) PaysonLinux 1.5 512 MB DDR2 533 Ram 2.8 GHz Pentium 4 HT Real 72m27.601s User 62m31.176s Sys 7m55.526s Machine Number Three: Dell Latitude D620 (laptop) PaysonLinux 1.8 2.5 GB DDR2 800 MHz Ram 2.0 GHz Core 2 Duo Real 60m58.084s User 53m14.081s Sys 7m15.363s Machine Number Four: Lenovo Thinkpad T500 (laptop) ** new system ** PaysonLinux 2.0.1 4 GB DDR3 1067 MHz Ram 2.8 GHz Core 2 Duo Real 21m19.746s User 37m14.059s Sys 4m33.276s As you could imagine, I'm quite happy with my new Thinkpad!
