The price of dynamic memory: Allocation

The price of dynamic memory: Allocation

Posted on July 25, 2020March 19, 2022Author Ivica BogosavljevićPosted in C++ Performance, Performance, Standard Library and Performance4 Replies

We talk about how to speed up your program if your program is taking time to allocate or release memory.

There are a subset of problems in software development that can be traced back to system calls or signals. Learn about STRACE, tool that let you trace system calls and signals and that can help you quickly figure out the origin of those problems.
