uddeIM running slow when sending message

Hi,

after trying uddeIM with success, i installed it on a website.
However, on this website uddeIM is very slow when sending message (new message, or reply).

I tryed to disable some extensions but nothing better happened.

Someone have an idea ?

Thanks

There are no time consuming functions or queries when you reply to a message or write a new one. Maybe it is a temporary effect with your db server.

Maybe there is not, but that kind of answer dont help me.

The effect is not temporary because it's the same today.

Another idea ?
