This isn't necessarily correct. Many modern compilers (e.g., C# and F# compilers) will do error recovery and keep processing as far as they can go, accumulating errors in the process. These same compilers are not different from that used in the IDE - they are one and the same. And finally, modern compilers can also be tuned based on usage, such as enabling batch mode to optimize for speed in a single thread or using as many threads as are available to optimize for IDE scenarios.
