Jaspersoft reporting server running extremely slow when viewing an adhoc or even creating a domain

[timy2]

Hi, 

I'm currently using jaspersoft along with amazon redshift. My problem is though that when ever i try to view one of my adhocs or even create a domain, jaspersoft runs extremely slow. 

After looking at out ec2 instance, its telling us that their no load on our system at all, running at less 1% cpu usage and less than a gig of ram. 

Is there a reason why this could be happening and if so, what is the best course of action to fix the problem .

Cheers

Could it be a Java problem? Is there enough memory allocated for Java Heapspace etc.?
