Each time I send a message to other user, or I update the journal, it spends around 5-10 seconds.
Its a new dnn Install, dnn 6.0 and the latest version of active social.  We have only 5 users.

Its a shared hosting in powerdnn, the rest of the app works fine, except send messages to other users.

Any solution?

How were the users created?

When exactly does it slow down, upon loading the page, or when you try to send the message?

The users was created by dnn login control, if you want i can create some users by social activity module. I didnt know it have some diference.

The slow process begins when i click the button for send, it opens a popup for 5-10 seconds.

Users created by the DNN control are fine.

Are you getting any javascript errors on the page, or anything in the DNN Event Viewer?

Nope, no errors. its all normal.
Do you want create a user and test?

I will send you a private message regarding this.
