Hi There I have followed the perfect install of ISPConfig 3 for centos 6. All went all. The problem I have is that 2 out of the 20 sites I have are randomly running really slow, 3 / 5 seconds to load a page. One of the slow site is just simple html pages and the other is a wordpress site. All the other sites combination of word-press and other php / mysql sites are running fast. I have had this problem in the past, and to resolve I just deleted the site, and re-created it, but now the problem is starting to happen on other sites I want to get to the bottom of it. Any ideas where to start looking? "TOP" doesn't show any high CPU / IO usage, the site are all low traffic.
Thanks for you reply, there is nothing new added to the error log : /var/log/httpd/error_log when visiting the slow sites. Although I did notice that the time was out by an hour, adjusting to system time to the correct time does seem to have made an improvement? Not sure if that is a just a co-incidence or not? I'll test it again / check logs later to see if problem returns. Thanks
