how many plugins you're using, you might want to add a screenshot.

did you often edit posts ? if so then you should disable post revisions, also install cbnet Ping Optimizer plugin so your site dont ping everytime you edit posts.

Also, you might want to use gzip and html/js/css minifier, I suggest you install WP Super Cache and WP Minify for that purpose.
