Hi,
We are setting Piwik on AWS (EC2 + RDS) to monitor 90 websites, for a total of 3.000.000 pages views each day.
Archiving is taking more than 4 ou 5 hours.
I set a cron job to run archive.php each night at 2:00. In the web interface, I leave the default value for “Reports for today (or any other Date Range including today) will be processed at most every” : 3600 s.
=> Do I have to set to 86400 (24 hours) for better performance ?
If my understading is correct, I should say no.
2/ Multiple archive.php
I read different threads and trac tickets (#4903) talking about using multiple instances of archive.php (when it actually launchs, the CPU never gets higher thant 30%).
I saw that we can specify which sites to archive with the option --force-idsites.
=> Can we create multiple cron jobs with different idsites and launch them simultaneously ?
Thanks for your help,
Regards,
Fred
