Better WordPress Google XML Sitemaps - ANyone Tried It ?

ofc it is, it splits maps to 5K posts or less, from original that was 50K and does not stress server that much.

If you have lots of posts you should use it, but if you have low number of posts not will be difference.

The author says that need less resources than other sitemap plugin.

Anyways try it and check results is the onle way to be sure that is better

That's not exactly correct.

The problem with the traditional Google XML Sitemaps plugin is that by default it rebuilds the sitemap when you create a new post. Even if you only have a few hundred posts, this creates a noticeable slow down. Of course, the way around this requires that you turn off automatic rebuilding and setup a cron job to rebuild it. Unfortunately this can mean then when a search engine crawls your site, the sitemap might not be fully up-to-date, as the cron job might not have run yet.

I switched to BWP sitemaps a few weeks ago and couldn't be happier, especially since I'm dealing with over 30,000 posts. It gets around the resource-usage problem in two ways. Firstly it allows you to split your sitemap up into smaller sitemaps (as mentioned above), all of which are linked together via a sitemapindex file. When you create a new post, only of of these smaller child sitemaps gets updated (i.e. the one with recent posts in), and this saves alot of CPU power. Secondly when you create a new post, it only pings search engines and doesn't rebuild the sitemap until a spider crawls your site. The benefit of this should be obvious but basically, the rebuild only takes place when it needs too.

As you can probably tell, I am a strong advocate of the BWP plugin and I recommend more people try it out.

N.B. You only add the sitemapindex in Webmaster Tools and Google/Bing does the rest.
