Management > "Last WebAdmin Sessions" very slow to load

unfortunately clicking on Management in webadmin takes up to two minutes on our SG430.

It loads "Last WebAdmin Sessions" and shows changes made by admin users. This is a useful feature.

This seems to crawl several logs and just takes it's time.

Unfortunately this slows down using the other sub-menus below the Management section because you need to wait that time.

Can we speed this up some how?
