Saving XML to cache takes a very long time

I’m on UAAS. We have roughly 700 contentXml items. We are seeing the following entries in our log files and the site becomes unresponsive when publishing new content.

22:30:56.020	INFO	umbraco.content	
Saved Xml to file.
22:30:31.497	INFO	umbraco.content	
Save Xml to file...

Note the timestamp is ~25 seconds to regenerate the XMLCache

Should it realistically take the site offline for that amount of time? What happens when we get above 2000 articles? Is this purely processor, memory, hdd write time going on here?
