The web server with Kentico 12 Portal Engine installed is experiencing CPU spikes. When I performed a CPU dump, it indicated that the cause was related to code at the section responsible for creating tags. How can I investigate further to understand why tag creation is causing CPU spikes, and how is regular expression (regex) related to tags?
