A rewrite makes sense for two reasons. 1: No two people on your team understand the code from start to finish, or 2: (as in this case) the current stack cannot perform to the standards required, and another stack can. Too many people just want to remix code or rehome it, taking the papers out of the old book and putting them into a new cover. At the very least, take the time to make sure you fully understand the system before you replace it. Actually read the source code before a rewrite.
