Errors are important, even very small percentages

• UDP and multicast are extremely sensitive to frame losses (NFS is particularly sensitive).

• Long ack times and large transfer sizes make the problem worse

  • Are 32K NFS frames much worse than 8K?
  • Does shortening the 'timeo' in the mount options down from 1.1 seconds help?

• At GbE speed, throughput losses can hit 7.5% with a frame loss rate of 1/10,000%.
