Hi, two days ago I upgraded our live server with ZF 1.5.0PR which caused a serious performance issue. The whole site slowed down immediately.
First I did not know what the real problem was because at nearly the same time a content grabber started to run his bots to grab our content. But after blocking his ips the performance was still bad compared to the time before upgrading to ZF 1.5.0PR. So today I switched back to ZF 1.0.3 and the performance was up again. With ZF 1.0.3 the load average is almost all the time lower than 1. With ZF 1.5.0PR is was almost all the time between 4 and 6. I was not able to identify the bottleneck because my first priority was to get the site back to normal. Hay anybody else upgrade an live server with 1.5.0PR and encountered similar problems? Has anybody any idea what could have caused these problems? Best Regards, Ralf
