If you need to dynamically trace Linux process system calls, you might first consider strace. According to a performance test conducted by Arnaldo Carvalho de Melo, a senior software engineer at Red Hat, the process traced using strace ran 173 times slower, which is disastrous for a production environment. The answer is YES.
