My page takes 2s after connect before the 1st byte is sent to the browser. I'm using stock WP with about 5 plugins. My CPU usage is usually fine but it also spikes to 90%+ without anything special happening and I don't know why.
I check sites using tools.pingdom.com
Is my host just slow? What makes this 2s wait? Is it the CPU? RAM? What do I look for in a host, how do I find one that's faster?
