WebMay 1, 2003 · This is exactly what malloc() does. It aggregates a lot of smaller malloc() requests into fewer large brk() calls. Doing so yields a significant performance improvement. The malloc() call itself is much less expensive than brk(), because it is a library call, not a system call. Symmetric behavior is adopted when memory is freed by the process.

WebTrace all methods of a class using a module-named logger This is the simplest way to use the autologging.traced decorator. All non-special methods of the class are traced to a logger that is named after the containing module and class.
