I'm working on a plugin that will auto-tag my posts (it's for a very specific, single project only). It will apply 6 tags based on the content of the post.
Forward thinking, I wonder if the number of tags that will build over time will eventually begin to affect performance?
I am doing it to add a bit more "width" to my index as to assist my related posts section with actually linking to related posts. :)
If the site builds to thousands of tags will there be a noticeable effect? I don't know WordPress well enough to know if there are subroutines using the wp_terms and wp_termmeta tables heavily.
Thank you in advance.
