Hopefully somebody can help me. I run wordpress on a vps with a single core cpu 2ghz+ and 2Gb of ram. Now, When I open a page, the cpu load spikes up to about 60 or 70 percent for about a second, this is not only on pages of my website, but also on the wordpress admin pages. It's "php-cgi" which causes the cpu usage spike. I tried to deactivate all plugins, still got the spike. I run php5 on my server. Is this normal? What can I do about it? I mean 70& loaded for a single user..? How can i simulate multiple visitors browsing my wordpress site?
