I’ve been working with Microsoft Forefront Threat Management Gateway (TMG) 2010 and it’s predecessors, Microsoft Internet Security and Acceleration Server (ISA) 2006 and 2004 and Microsoft Proxy Server 2.0, for more than 15 years. I’ve deployed TMG for some of the largest organizations in the world, and one of the most common deployment scenarios I encounter in the enterprise is the forward proxy server. In this role, Forefront TMG 2010 serves as a central point to aggregate access and to provide visibility and control for users accessing content on the public Internet. Over the years I’ve gained a lot of experience making TMG perform well under extreme circumstances. Under heavy load conditions, which are common in enterprise deployments, a seemingly benign configuration error can result in severely degraded performance. In my latest article on ISAserver.org, I share a few of the tips I’ve learned for extracting the most performance from the Forefront TMG 2010 firewall configured as a forward proxy server.
