My site page load times have been noticeably slow and my server suggested that it was due to your google xml site map plugin. I like your plugin but when investigating further in debug function i noticed it still had information relating to another plugin that was big and slow and since deleted and i was wanting that information removed out of the site map how do i do this? could this fix this issue?? Do i simply delete site map and start again or is there another way to not disrupt webmaster tools too much??
