Half of the URL's on the sitemap are indexed and the others are not found?

Hi Group Support,

I have use a third party XML generator compressed the file and loaded
into my server.

I have resubmitted the sitemap and the stats are OK on the goggle
sitemap.

What I have noticed that only half of the URL's on the sitemap are
indexed and the others are not found.

Please advise if I have not completed a task or the program is not
compatible with your system.

Thank in advance for the assistance in this matter.

Best Regards
