Umh...
Today's day of Cronjob... I make a cronjob for each site, at a distance of one hour from the other once a week.
Cronjob upload new content to MySQL, add new links to Sitemaps etc. Some cronjob last a few seconds 5-10-20 others are sometimes longer 2-3 min.
Today I began to see strange behaviors.
For example trying to install zip
Code:
root@ubuntu-2gb-blr1-14-04-3:~# sudo apt-get install zip
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages will be upgraded:

or occasionally visiting a site
Updating the page all back to work
Even nixstat from a few days, it's kinda hard to show me the charts.
I have added some site in the past few days, even from 2-3000 visits a day and are not all yet... the two most performing sites I would like to put on this server I have not moved them yet.
Are problems that can be solved with some optimization of MySQL (eg resizing tmp or caches) or is it already time to buy a larger server?
