I see what you are talking about... apparently every single time a Compiled HTML page opens, it calls a DCX web service (?) to determine if there are any comments.
That process has never, ever slowed anything down in my experience, and I use CHTML because of the speed... so, in your case, there may be something special. Perhaps it is a firewall issue.
I think the blogspot.com.otherTLDs are straight mirror sites. No, there have been no updates to the blog for a long time.
