Anyone here use ActiveCollab?

Anyone here use ActiveCollab?
I just installed it on my 'regular shared' hosting, it seems to lag/slow like mad.
I am wondering if it requires more than just 'shared' hosting? like a VPS for it or something?

No one uses project-management software? ouch :|

I do. I'm on version 2.3.5. It's very speedy but not responsive (for example I can't view some of it on my iPad). Not sure what version you have but I have v2.3.5 as this might help with the speed on the server. PM me for the link as I'm very new and am not allowed to post links yet. ;(
