How much bandwidth utilization % affects throughput
Posted on 2013-12-10
We have a 3750x switch stack & Im getting a number of questions around the possibility that our switch ports 1Gb switch ports are causing a bottleneck...
When I look into the statistics we average around 250Mbps (so around 25%) Occasionally we peak around 80-90% during nightly backup windows...
So even the question is...
Can higher utilisation cause latency/bottleneck even though its not at 100% ?
Im not sure how much to allow for TCP overheads etc but Im pretty sure that unless its not hitting 100% in both duplex directions then there shouldn't be a problem ??
