Bring your expertise and questions on all things logging and on operational visibility to find answers, best practices and cool stuff. This is an optimization that interferes with the basic mechanism of load balancing. 2009/04/18 - New benchmark of HAProxy at 10 Gbps using Myricom's 10GbE NICs (Myri-10G PCI-Express) Introduction. Firstly, HAProxy is missing a lot of the Application Delivery features of a full, modern, commercial ADC with a Web Application Firewall etc. pid = 1122 (process #1, nbproc = 1) uptime. 5% CPU on each core), while serving 5000req/s. Summary: Gregg O’Brien, a Microsoft Premier Field Engineer from Canada, provides insight and walks us through how to configure DirectAccess in Windows Server 2012 to work with an External Hardware Load Balancer. Moving from a Hardware to a Software Load Balancer. Choose business IT software and services with confidence. The HAProxy service SHOULD NOT be run on a node of the RAbbitMQ cluster.
