Saving buttons and heavy attributes database

[wacommunication]

Hi,

I thought a week ago that removing some of the attributes from my database would solve my problem with my saving buttons. It did, but it brought a new one : the site was becoming really slow and stopped working this morning.

So i brought back my old ps_attribute and ps_attribute_lang tables with more than 100.000 attributes and my save and save and stay buttons are back to infinite turning state.

So i'm looking for an SQL query that would help me clean the attributes, and any related table, so that i could start working on my products again.

I'm a newbie, i might be taking the problem the wrong way, so i'm open to any suggestion to solve that problem...
