Stats won’t be quite as “live” over the next few weeks, as some automated processes run in the background to go through all of your sites’ history and summarize the data in highly optimized ways. At most points in the day, your stats will be fine! But when these new processes are running (once every 4-5 hours), the live stats updating takes a breather to let these run at full speed.
The choice is either, these two different processes compete with each other and slow each other down and hence make the site drastically slower for everyone, or a few times a day your stats lag a bit behind (by an hour at the most) but in turn the site is fast. I like the second choice better and hope most of you agree. I know one of the best things about Clicky is that the stats are never more than a few minutes behind real time, but this is something that we have to do! Trust me, the results will be worth it! You will start noticing a HUGE speed increase in the dashboard load time starting early next week, especially for those of you with higher traffic sites.
