*Performance analysis* ([[!wikipedia Performance_analysis desc="Wikipedia
article"]]) deals with analyzing how computing resources are used for
completing a specified task.
[[Profiling]] is one relevant tool.
In [[microkernel]]-based systems, there is generally a considerable [[RPC]]
overhead.
In a multi-server system, it is non-trivial to implement a high-performance
[[I/O System|community/gsoc/project_ideas/disk_io_performance]].
When providing [[faq/POSIX_compatibility]] (and similar interfaces) in an
environemnt that doesn't natively implement these interfaces, there may be a
severe performance degradation. For example, in this [[`fork` system
call|/glibc/fork]]'s case.
[[Unit_testing]] can be used for tracking performance regressions.
