[timpears]

I have updated my home page design and adding new articles for it and I want search engine spiders crawl my site faster.
which one I should choose between Ping website or resubmit sitemap? which is better?

It is advisable to update search engines about the changes you made so that spider begin to crawl the updated URLs as soon as possible.

Note: unnecessarily pinging sitemap may have a negative impact.

Pinging your site has a lot of negative effects, which will make your site vulnerable to spammers. So simply submit your sitemap to search engines instead.

I would do neither one.

Just login to Google's Webmaster Tools and have them fetch the URL.
