I have multiple Windows servers with 200-400 packets discarded / sec shown in Performance Monitor. Strangely, the number doesn't fluctuate and is static such as 357 received packets discarded and chart is flat. There is VMware article on increasing NIC buffer size but I would think discarded packets should be moving up/down in numbers not static. Is there something else I could look into? What are the negative effects of increasing NIC buffer?
