It is a server problem. You are not alone! Several hosts across the glob have been hit. Who hosts your site? Anyway, contact your hosts.
Hello, I updated my site to WP 3.5.1 and it got so slow too. When I am going to save a post in the admin area, it takes around 15 seconds.
Any idea?
My host is hostmonster

It may also be related to the mass attacks on servers – in which case, there is nothing anyone can do about it at this time. Contact your hosts to see what is going on there.
