According to C++ modules proposal:

1 Introduction

Modules are a mechanism to package libraries and encapsulate their 
implementations. They differ from the traditional approach of 
translation units and header files primarily in that all entities are 
defined in just one place (even classes, templates, etc.). This paper 
proposes a module mechanism (somewhat similar to that of Modula-2) with 
three primary goals:

Significantly improve build times of large projects
Enable a better separation between interface and implementation
Provide a viable transition path for existing libraries While these are 
the driving goals, the proposal also resolves a number of other 
longstanding practical C++ issues (initialization ordering, run-time 
performance, etc.).

Since header files are typically included in many other files, the growth 
in build cycles is generally superlinear with respect to the total 
amount of source code. If the issue is not addressed, it is likely to 
become worse as the use of templates increases and more powerful 
declarative facilities (like concepts, contract programming, etc.) are 
added to the language.

Modules address this issue by replacing the textual inclusion mechanism 
(whose processing time is roughly proportional to the amount of code 
included) by a precompiled module attachment mechanism (whose processing 
time—when properly implemented— is roughly proportional to the number of 
imported declarations). The property that client translation units need 
not be recompiled when private module definitions change can be retained.
