Questions regarding Architecture and Performance!?

Hello Arne,

first of all. Absolutely great Plugin! A five star review will follow.

I shortly looked at the sourcecode and it is very clearling engineerd, great! But neverthelesse I have a big Question: If in theory my page will one day have 200.000 posts, will your plugin have a very negative impact on perfomrance?

It would be absolutely great, if you could write (also in the FAQ) a little bit about the performance/arichtecture. Just a view questions as example bewlow, but it would be much more appreciated if you could write roughly, how the plugins works:

Sample questions (better is if you write the process from a technical perspective what the plugin does, then everything should be clear)

1.) Are the sitemaps generated “on the fly” when requestiong the sitemap.xml? (or are the generated by wp-cron.php and statically but somewhere)

2.) Does the generation lead to a “select * from wp_posts”? OR is there a brilliant logic included, that does this somehow incrementally? For example query only by date, sind the last time queired (so only new posts will be added and old ones have not to be queries again). So the “old” xmls will not be touched. only incremental small new xmls will be added.

3.) If this is done incrementally, are the sitemaps “aggregated” from time to time in one single file.

4.) Is stuff cached in memory

5.) If this is done with incremental generation of the sitemaps, how are they structured. By date? or by type…?

Thanks very much!!!
