errors in connection

looks like your server's bottle-neck is mysql database: 292.3% CPU

to verify this, you can put a phpinfo.php page under a slow site's document root, when you feel the site slow, access phpinfo.php, see if it's fast. this is because phpinfo.php has no access to database; if phpinfo.php is fast then problem is not at web server, most likely mysql database slow down the whole site.

hi
but you know I check the HTML websites with no data base, but they are also slow in compare with websites hosted on another servers...
