I think developers wanted to avoid script timeouts - that is if too many pages have to be parsed. It's an unelegant solution, even slightly lazy ;-)
That may be, but i set it to 30000 and at the moment i have no problems. There was no performance problems bevor i receive the message "to many pages". I will see what happens ;).
Isn't there a little script which purge the artio links every day automatic?
Thats not the best idea, because i did not want new links every day.
The first think is, that all links must be created and the second thing is, that my google link are not ok any more.
In some cases this is ok, because the links are clearly. In my case some Components dosn't make very good links (com_gigcalendar for example) but they are better then standalone seo from joomla ;).
