| 35 | IanMcDonald | 1 | This page covers the Kernel Compilation Benchmark, which is often used to provide a rough comparison of system performance. This page used to use a 2.4.19 default config to do this benchmark, this data still exists at KernelCompilationTimes2.4. The 2.4.19 kernel is a bit old now, and the 2.6 build process has changed a lot, so we've updated this to use 2.6.8 as the test [Kernel]. |
| 22 | DanielLawson | 2 | |
| 3 | A few things have changed - there is no longer any need to run make dep or make modules, so there will only be one time output. You will need to run make defconfig first, otherwise it will try to build a host-specific config for your computer. | ||
| 4 | |||
| 35 | IanMcDonald | 5 | It's still important to perform the compile as soon as you untar the [Kernel] source, to ensure the source is still in disk cache. |

| 19 | If you have a machine with more than one processor, you can use make -j n .... where n is the number of cpus + 1 | ||
