Of course there should be. Unfortunately I never had a chance to try how big the performance gain will be. But maybe someone else here can answer that.

I'd not noticed that enhancement (I'm running 6.2.0-0013 so I'm already covered for this). "a sort of load balancing"; Should I not expect a measurable performance advantage with this setup then? jh _______________________________________________ Linux-PowerEdge mailing list [email protected] https://lists.us.dell.com/mailman/listinfo/linux-poweredge Please read the FAQ at http://lists.us.dell.com/faq
