Sometimes you get a higher network latency during certain periods of the day.
You notice the trend of growing latency during business hours.
It may seem trivial, but maybe it is useful to underline, that this indication can help identifying overloaded network devices.
In fact, under high load different network devices show different performances. Especially devices that perform routing / filtering / tagging are sensitive to the amount of packages that have to be processed.
The greater the operations, the device has to perform, are the slower the processing queues are emptied and therefore network latency increases. When the latency becomes sensitive to higher workload, you should check the configuration of the device and possibly adjust the configuration to its processing capabilities. By configuring the monitoring of certain network sections with NetEye RUE, we are able to highlight such behaviors and to react in the appropriate way.
