12.5. Install and Configure Performance Tools

The next step in the hunt is to install the performance tools. In this case, neither ltrace nor oprofile will be of help. oprofile is used to profile applications that use a significant amount of CPU time, and because prelink uses only about 3 percent of the CPU when running, oprofile will not help us. Because the prelink binary is statically linked and does not use any shared libraries, ltrace will also not help us. However, strace, the system call tracer, may help, so we need to install that.
