Certainly, doing things on the client-side will avoid a round trip. The penalty of a round-trip varies widely depending on how your application is deployed (intranet, extranet, internet or mobile). The big benefit of JavaScript in the browser is that it can be used to update a page rather than requiring requiring a full page reload for any interaction. Using Ajax, the browser is able to make non-blocking calls to a server in the background. Both of these aspects of JavaScript are fully exploited by Wt. It is true that by default, since you program using C++, Wt will make a (at most single) round-trip to the server for each interaction, but you do have the ability to optimize this away by moving things to JavaScript when needed. There are ways to connect JavaScript to events, and/or to provide a JavaScript implementation for a C++ method. The latter method has the benefit that your application will still work consistently for a non-JavaScript browser. There are other situations where Wt will be more performant than client-side JavaScript: most notably on slow JavaScript engines (like Internet Explorer), doing many small updates client-side (DOM manipulations) can be slower than fetching a snippet of HTML rendered server-side.
