7.5.1 System/Compile Time and Startup Parameter Tuning

We start with the system level factors, because some of these decisions must be made very early. In other cases, a quick look at this section may suffice because it not that important for the big gains. However, it is always nice to have a feeling about how much one could gain by changing things at this level.

The default operating system to use is really important! To get the best use of multiple-CPU machines, you should use Solaris (because its threads implementation works really well) or Linux (because the 2.2 kernel has really good SMP support). Also, older Linux kernels have a 2G file-size limit by default. If you have such a kernel and a desperate need for files larger than 2G, you should get the LFS (large file system) patch for the ext2 filesystem. Other filesystems such as ReiserFS and XFS do not have this 2G limitation.

Because we have not run MySQL in production on that many platforms, we advise you to test your intended platform before choosing it, if possible.
