Piwik will run through the logs and compile all your reports for each day, week, month and year. How long the process will take depends on your traffic, number of visits and pages, on the number of WEBSITES you have setup in Piwik and of course on your server performance.

For example, using VERSION 1.3 on a single core duo2 server with 3GB of ram, Piwik ARCHIVING process takes about 2 hours for 400,000 pages per day (and more than 6,000 websites). We are constantly IMPROVING Piwik performance.
