This thread is to point out limitations about generating sitemaps with tens of thousands links.

So many users experiment issues generating very large sitemaps, and maybe they expect this can be accomplished in a snap.

A lot of trouble occur when for example 50.000 records needs to be managed for a single sitemap generation, mostly due to server settings first of all.
Mainly issues that prevent a complete sitemap generation in these cases are:
- Server timeouts
- Memory limit

This should let you understand that generating a full sitemap for say 100.000 links also using a good component like jsitemap can't be viable if server settings and resources are not adequate.

For this is recommended to contact us asking for a free trial and an on site demo in all these cases.

The same can occur generating images sitemaps. For images sitemap a crawler needs to scan all the links on your site, and this is an quick operation for 100 links, but for 1000 links can require several minutes. On server machine that have a timeout set to 60 seconds won't be possible generate a full images sitemap.
Again, contact us to test on site if right setup can be found for your server.
