Performance issue while generating Dashboard for more than a week

Hi,

I am using piwik to track a website which has about 100K visits per day. I am using cron job to archive reports every one hour but still while opening the dashboard for more than 1 week, data is not displayed.

It says the “Loading data…” and even after 2 hrs no data is displayed on dashboard.

Did you disable browser trigger archiving in General Settings?

is the archive.php running until completion?
