I have a problem when i'm trying to generate a sitemap.xml. It's very very slow:
Pages added to sitemap: 3021
Pages scanned: 3135 (247,943.1 KB)
Pages left: 685 (+ 4303 queued for the next depth level)
Time passed: 2:40:17
Memory usage: 14,117.0 Kb
Total time necessary to generate complete sitemap.xml would be seven hours around!! How is this possible?
