Publishing and saving load times

hi dp, i recently picked up a ping list from this forum and now whenever i publish or save a post it takes a long time and always gives me a blank page when it is done loading. the post is saved or published, but i get a blank screen. is this from the ping list?

 

This link may help you

'Publish' is terribly slow and returns blank page

Put a lot of ping servers may cause publishing slower

 

thanks a lot i will sift through my ping list and take out the bad ones
