Linting a large amount of files takes some time. This is normally not an issue, when running the analysis on build servers. The speed of PC-lint Plus is generally acceptable.

However, this is still a source of frustration and seemingly wasted time for developers, when linting large project locally. A typical workflow while working on code is that a developer will often run lint locally for small incremental changes. (while changing code or while fixing lint messages) Since PC-lint Plus has to run through all of the source files again to properly check global rules, it is frustrating to have to wait for exactly the same analysis for >100 files, when you have only changes in one. A caching function, similar to ccache would be very welcome there. Something like “same cpp file, same included headers, same options, ….” -> use previous analysis results.
