[Virtuoso-users] performance testing

[Ward Blondé]

Hi,

I was running a query, which took 20 seconds to return the answer. After 
running a similar query in between, I was running the same query, which 
took only 2 seconds any more. What could be the reason of this?
And what would be a good way to test the worst performance of the 
queries I write?

thanks,

Ward
