• Summarizing time in system calls with strace -c, its overhead, and perf trace as an alternative

  strace -c counts time, calls and errors per system call instead of printing every call, but strace's own manual warns that a traced process runs more slowly than an untraced one; perf trace, described as a strace-inspired tool built on perf_events rather than ptrace, is the lower-ceremony alternative when that overhead matters.
