Depending on what hosting server provider you are using and how well your Movable Type templates are coded, you may notice that publishing or updating an article takes way too long to complete
The best way to troubleshoot this is to consider using a Movable Type expert and have him optimize your Web site templates for optimizing publishing times
PRO IT Service successfully optimized a bunch of Movable Type Web sites for reducing the time required for publishing new content without sacrificing anything
All we do is to optimize the tags and the templates organization so that Movable Type will use as low server CPU as possible
An alternative for this templates optimization is to switch to a better hosting server
