Question about Inactive Script Users

[phanhan]

Hello everyone.

I've got an SMF 2.0 forum that is now running painfully slow.  I am wondering if it possibly has to do with Inactive Users.  I'm not sure I totally understand but this thread

http://www.simplemachines.org/community/index.php?P=902819458f82fc917fa6d8e91a4cc994&topic=293441.0

recommends running this script here:

"Run the mark read for inactive users script periodically. The log_topics, log_boards, and log_mark_read tables are not the best designs, and for some unlucky folks end up dominating their database. Pruning them can help.."

My problem is this:  I do not have admin access to my site since I am shared hosting.

So how can I clear out inactive users?

1- "inactive users" are unlikely to be causing problems, unless you are talking THOUSANDS of them  -- and even then, not so much

2-you don't have admin access?   WTF?
