You chose this to be your first post?
Using peak theoretical numbers doesn't always apply to real world performance. PCI based ethernet usually caps out at about 500-700 Mb/s depending on the situation. PCI-E will use the full 1000 Mb/s (more like 950 or so)
Besides even going by peak theoretical limits as you did, 133 MB/s is not "plenty" of bandwidth for Gigabit ethernet (which is 128 MB/s peak). It's barely within the limits, which is why we see real world performance work out much lower.
