Anyway to make this theme load faster?

.htaccess is as follows:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END

The hosting is godaddy. I have seen other postings about them being slow, but I have other sites on godaddy without this issue. I will disable all plugins and enable one at a time as you suggested... Thanks!
