How does Logtalk performance compares with plain Prolog and with Prolog modules?
Plain Prolog, Prolog modules, and Logtalk objects provide different trade-offs between performance and features. In general, for a given predicate definition, the best performance will be attained using plain Prolog, second will be Prolog modules (assuming no explicitly qualified calls are used), and finally Logtalk objects. Whenever static binding is used, the performance of Logtalk is equal or close to that of plain Prolog (depending on the Prolog virtual machine implementation and compiler optimizations). You can find here some simple benchmark tests using some popular Prolog compilers.
