Performance

Raw performance delivered by current Mellanox-based InfiniBand hardware is quite impressive and peak bandwidth is primarily limited by the PCI-X bus implementation on the system. Figure 1 illustrates the raw performance available using the Mellanox VAPI interface on a 2.4ghz Dell 2650 and 1.8ghz Macintosh G5.
