sql performance, visual studio

I'm using linq2sql and .net 3.5 with vs2010. I'm experiencing bad sql performance when i run my program through vs2010, but not when i execute the same debug enabled exe outs开发者_开发百科ide vs. Whats going on here? Any ideas?

If the program is running ok outside visual studio then maybe the sql or linqtosql isn't the problem. If you run it through visual studio with the debugger disabled is the performance better?
