How does SEF Advance perform on high-traffic, large sites with much content?
Unlike other SEF components, SEF Advance doesn’t store URLs in database to later look them up for conversion. Instead, SEF Advance does all the URL conversions on-the-fly. This method has proven to be more effective in terms of performance because it avoids dealing with database searches on very large, non-indexed, duplicate-entries tables. Additionally, SEF Advance features disk cache option for further decreasing the load on your database. SEF Advance has been successfully running on many large sites during the years.
