The largest constraint on using vSphere FT is that it requires uniprocessor virtual machines. To mitigate the potential impact of this:
• Use the highest-performance CPU cores available for the hosts running the FT virtual machines. Processors with many cores do not help and often have unfavorable performance trade-offs.
• Ensure the networking infrastructure can handle both worker traffic as well as FT logging traffic, or separate the FT logging traffic onto a dedicated network.
