Comment 22 for bug 87796

It is definitely trying to grab information each time you click on the clock applet. (I checked my network usage.)

If you set evolution to work in "offline mode" (File>Work Offline) everything is as fast as before. Right now I have 5 calendars enabled and have no lag!

Not a big deal for me because I don't use it to check email. It's nice to see it get fixed though!
