Item12: Server time-outs on svg load / session_id issues / pregenerating clusters in mysql

Possible solutions:

• Can we clean the mysql database to speed it up? Just flush or clean it. Automate the cleaning.
• Store the default cluster maps in the mysql database. Most of the time is spent calculating the strength of the ties for clusters, pre-storing the clustermaps would skip this step. This should involve solving the bug caused by session_ids that users cannot load multiple maps nor that the same map is loaded my multiple users.
• issue4.php seems to have a lot of redundant data retrieval and checking. In general we should look at / rewrite the whole publishing process
• see also other item on cleaning / flushing
