PHP sessions use locking to avoid race conditions. So you sleep for 20 seconds keeps the lock for just as long, this has the effect of blocking all other scripts for the same session. To avoid this, grab the session data you need, and close the session as fast as possible. Additionally, it's probably a very bad idea to keep the web server waiting for 20 seconds for no good reason. Why not have your javascript do the waiting?
