Anyone using SiteCatalyst with CM1?

Would like to hear if anyone is using SiteCatalyst with CM1. I have the codes implemented on my site and have had performance delays show up when trying to edit a page. Anyone have SiteCatalyst and having similar issues or have SiteCatalyst and noticed no performance issues? Thanks for any input.

I just wanted to bump this topic up because I too would be curious to know if any other customers use SiteCatalyst, and if so, have you encountered any issues similar to what Jerome is describing?
