Translating code on the web server every time it's needed is certainly more expensive performance-wise than executing precompiled code, as it requires more effort on the part of your machine's processor. The good news is that there are ways to speed up scripted languages, including techniques such as code caching—caching the output of a script for reuse rather than executing the script every time—and persistent interpreters—loading the interpreter once and keeping it running instead of having to load it for every request.
