Ethernet
Theoretical Maximums for common devices (Hard Limits)
- The below limits are based on the assumption of managed switching infrastructure and server grade network interface cards.
- 32MB is generally the lower memory limit for server grade managed 1GB switches.
- 1GB network cards typically built into servers are consumer grade and/or contain < 1MB of cache.

Special Considerations:
Jumbo frame support os,nic,switches,vm?
Offloading support in os,nic,vm?
Often bonding more than 1 or 2, 1GB interface(s) per core is actually slower
For best results bond at maximum 8 1GB channels
