If you're an AdSense publisher or a web surfer going to AdSense-supported sites, you've probably seen how slow the pagead2.googlesyndication.com gateway can be.In fact, when that particular address is called up, the entire web page seems to freeze for 10 to 20 seconds.
This apparently has nothing to do with people's firewalls, OS or browser.A large number of AdSense publishers have pointed out that these problems have started after Google purchased its competitors and started integrating their lousy advertising inventory in the PPC ad engine.
If you're looking for culprits, it seems you'll have to look at
DoubleClick which is probably dragging its feet and slowing down the whole Google AdSense operation. It's a theory that's as good as anyone else's.
In the absence of a formal Google response, we're basically left out to speculate about what causes the pagead2.googlesyndication.com gateway to be so supremely slow.Let's hope this issue gets resolved...
