sleeping processes

[hessodreamy]

Just a quickie: What does it mean when a process is sleeping, but there is no associated query?
ie
Command: Sleep
Time: 8434
Info: Null

I have a handle of such processes under the user for php. Might they be slowing things up?

Sleeping processes are doing just that -- sleeping. They are not active and not taking up any extra memory.

They are processes that are waiting for input from your client software (either PHP, Apache, or MySQL clients).

They do not negatively affect performance.

HTH!
