Dispelling Bandwidth 
Myths in High-Performance Networks

Increasing network bandwidth delivers limited performance gains. Find out what key areas to focus on instead to reduce latency and congestion, and to improve workload completion times.

More Bandwidth ≠ Better Performance

Bandwidth alone won't solve performance issues, there are other, more important factors to consider.

It's not how many gigabits you have, but how you use them.
Slide Image
It’s not uncommon for 90% of the traffic in traditional spine-leaf architectures to be routed through 20% of the links, creating route collisions and driving up congestion.
Slide Image
Increasing bandwidth doesn't resolve the efficiency problem, but makes it easier for more data to travel over the network faster on its way to the switches - increasing congestion and workload latency.
Slide Image
Oversubscription compounds the problem for both scale & budget.

Don't just take our word for it
