I have been researching the pros and cons of suPHP vs FastCGI for performance and security. FastCGI has the security benefits of suPHP based on ownership and is fast at the expense of memory. FastCGI also will allow for the use of caching. Leading to better methods of increasing site (WordPress) performance. suPHP is secure. An consumes more cpu cycles instead of memory. In general suPHP is slower but can handle higher traffic loads more gracefully (when overloaded). I am currently using suPHP and we are starting to get regular oom. So switching to FastCGI at this point would be a bad idea, I think. Is it possible that once the database/page/etc caches are built (for the most common queries etc) the overall resource usage would become acceptable? We are upgrading to a dedicated and would like opinions on using FastCGI or stick with suPHP. I'm planning on trying FastCGI before the upgrade just to make sure everything works as expected. Thoughts?
