Can any one help on what optimization is needed?

load sometimes goes as high as 30 few times a day

I’d make sure you have the latest version of iworx-cp installed. the iworx.php cron job is very lightweight and I doubt that it alone is causing the problems (but could be part of a larger problem by adding load to the system). You can try disabling the main iworx.php “fively” cron job in the nodeworx cron editor and see if it “fixes” the problem but you’ll do this at the cost of bandwidth and storage accounting.

Please can epxlain that?

Thankyou

What it means to me is…

The Iworx cron job that runs every 5 mins to create the graphs and monitor storage / BW. You can go to Cron in nodeworx and disabled the 5 min cron job, but then you will no longer be monitoring the storage and BW.

whats up ifmove that stats every 30 minutes, or hourly?

Good question. Maybe the graphs would still be whole, just not updated very often, but on the other hand when I had a problem with this cron and rebooted, the 5’ly did not fill in the “missing time” from the graph.
