MWUG wp-myths
The document discusses several common myths about WordPress performance and security. It notes that while some plugins can slow a site down, others speed it up or have no effect. Inactive plugins and themes still need updates for security. Revisions and trash do not significantly impact performance. WordPress scales well for large sites. It is used by major companies and organizations, not just blogs or amateurs. WordPress security has improved, but proper precautions like updating plugins are still needed. Function calls are cached so removing them prevents functionality.
