Which in turn reduces the application startup time by avoiding the need to compile the code at ru time again and again. Once an NGen is run against an assembly, the resulting native image is placed into the Native Image Cache and when we run the application it uses the Native cache instead of the recompilation of code. The runtime can use these native images from the cache instead of using the Just-In-Time JIT compiler to compile the original assembly.

Ngen also allows sharing the same Native image cache with another application so it is helpful in terms of memory usage.
