I successfully created a free sitemap online. It was relatively fast. I purchased and installed sitemap with GoDaddy. Now I have a problem. The process is very slow. I made several attempts but there is no result for over 48 hours. Is it possible to run a map one time on any other server? Is there a way to do it on xml-sitemaps.com? 

how manya pages do you have crawled so far? What is the total number of pages on your site?
Thank you for reply.
This is what i have so far. Please advise.

I see that it scanned more than 1000 pages, but added to sitemap only 656. It meas that it's possible to improve crawling speed noticeably using Do not parse/Exclude options. Please PM me your generator URL to check this.
