Greetings,
I am having issues with performance with MS Network Load Balancer for my webservers that are running as virtual machines.
this issue is occurring whether the NLB is configured for Unicast, Multicast, or IGMP Multicast.
I can get NLB to work in every configuration, performance is abysmal.
the performance drop can be measured with IE developer tools and File transfers to the NLB vs accessing a server directly.
We have added the Static ARP multicast address to our router.
we are using Fortigate router/firewall, DLink 1210 switches, Broadcom nics on dell servers running HyperV.
Can I get some ideas to improve performance?
