Performance Considerations
Performance is a key aspect of any software
system. Nowhere is this more true than in the kernel, where small
performance problems tend to be magnified by repeated execution. For
this reason, it is extremely important that your code be as efficient
as possible.
This chapter discusses the importance of low interrupt latency
and fine-grained locking and tells you how to determine what portions
of your code would benefit most from more efficient design.
