"description": "The number of milliseconds [enhanced-resolve](webpack/enhanced-resolve)'s cached file system should use for cache duration. Typicially you won't have to touch this - the default works well for repos up to 5000 modules/ 20000 dependencies, and likely for numbers above as well. If you experience memory problems on a (humongous) repository you can use the cacheDuration attribute to tame enhanced-resolve's memory usage by lowering the cache duration trading off against some (for values over 1000ms) or significant (for values below 500ms) performance. Dependency-cruiser currently uses 4000ms, and in the past has used 1000ms - both with good results."
