Why apps are slow over wifi?

[jev425]

I have noticed that certain apps seem to load pictures or articles slowly over wifi(example being instagram). I have done speed test over wifi and I am getting very fast speeds so not sure what it could be. Any ideas?

Parallel loading of content? And pre-loading of what is logically next?
High speed, but packet loss? High speed, but a high latency?
Instagram over wifi is as snappy fast for me as it is over ethernet

Do you have background refresh enabled? If not, perhaps consider trying it to see if it makes a difference for you.
