Thanks Andrew. I think we have this resolved. It wasn't the campaign, it was the result of the upgrade - the upgrade was the only change. Here's what we did in the meantime: - deleted all our old campaigns. I suspect this is what the problem was. We had campaigns going back years that were completed but still in the database. - re-ran the maintenance schedule. - in the control panel ran all the maintentance scripts. And very shortly thereafter it seemed to get back on track. Thanks again for your input.

Bit of an old topic, but there's no specific number for this. Instead, try using http://www.webpagetest.org/ . to check the speed of your websites and determine if there's a speed problem and if so, where. For example, one of the things I do us use a professional DNS system that has DNS servers located all over the place. DNS lookups are then done close to the visitor, speeding things up quite a bit. I also am colocated in a facility that has peer sharing with most of the main ISP providers in my country. So when visitors access our sites, there's not many hops to get here. Both of those things can make a visibile difference without upgrading hardware. More ram is always an easy fix too. 4g seems low, 16 gig would be better. And failing that, a simple bump to an SSD hard drive can work wonders as well. Most of the other hardware stuff will likely have a small impact compared to all of the above.

Just upgraded from openx to revive ad server and since the upgrade the ads have been severely underperforming. Originally we were on openx 2.8 and I had someone fix a similiar problem years ago. Here's an example of the daily impressions from one ad campaign: 16000 16000 9600 3500 2400 1500 1700 1500 500 today to so far. In order to serve all the ads, we need to be serving the 16,000 per day, not 1500. Any ideas on how to correct the targetting?
